LP Vinyl: Quality, Pressing, Label, Weight, Where to Buy ???

@jasonbourne52 nailed it.

There is no end to the discussion of original pressing vs re issues.  I for one have had very poor experience buying used vinyl.  The odds of finding a used LP that does not have some damage are slim.  An LP can appear to be pristine, not a mark on it and still sound terrible when played.  Then you have the re issue.  New LP's that have been re mastered from the original tapes and properly pressed should be indistinguishable from the original, or at least so close that most of us are not going to hear anything but beautiful music.  Many companies like Blue Note, RCA and Deutsche Grammophon  are mining their vaults for opportunities to re monetize their assets.  We are not the beneficiaries of this exercise.  Pristine re issues of great music.  Are they all gems?  No. You still get poor pressings and damaged goods but that should not deter you in your quest to build a library of great vinyl.  My personal recommendation is buy through Amazon.  First, they have an incredible amount of re issues and re masters on both vinyl and CD.  For example,  RCA produced a remastered box set of the 7 albums Paul Desmond recorded on their label.  Each disc packaged in a cardboard sleeve with original cover artwork and liner notes.  $35.  About the average cost on one new LP.  Secondly, if you are not happy with the product they will refund your money and ship the product back at no cost to you.  Happy hunting.

I was in you same situation a couple years ago. Now, absolutley back into vinyl after may absence since the mid-80's.

I have purchased mostly period pressings, and if in VG-NM shape they can be outstanding (depending how the original was recorded, engineered, mastered, etc).  Rarely do I buy anything less that a stated VG+ condition. 

As stated, Discogs. First, I began my Discogs journey by cataloging all my existing music into Discogs. Took some time, but worth it. You will find you will then have all the information you need in obtaining and searching out a particular pressing that are available, and also available for sale. Then, I began purchasing from various sellers on Discogs. This has been hit and miss. Try to stay with sellers who have close to a 100% positive feedback, that means even 98% may not be good enough. As you begin purchasing, you will probably find reliable and consistent sellers, and do repeat business with them. I find some have a very different idea what a VG, VG+, and NM may be. And that can be frustrating.

eBay. I have actually had very good luck on eBay. Plus is you can usually see pics of the actual album(s), which can give you a better idea it's condition. And, as with Discogs, I save sellers I get consistently good vinyl from, and repeat purchase from them. 

In general, I have purchased better overall period pressings on eBay vs. Discogs.

New vinyl, there are many good outlets available to you. Popmarket is a good place to start, as is Acoustic Sounds. I have actually got some very good priced vinyl from Target as well, albeit the selection can be limited.

Have fun, and enjoy vinyl again. I know I am. But, it is a very large rabbit hole.

I buy from a variety of places - Amazon, ElusiveDisc, Acoustic Sounds, Ebay, Discogs and of course local used record stores.  Of all the places, my favorite is Amazon.  Can't beat the two-day Prime delivery as I hate waiting for things.  Out of maybe 100 albums, I've only had to return two - that's not too bad.  Their customer service has also gotten better and their price for new albums is pretty competitive.  At one time, Amazon even mailed me an album in a plastic bag (and I even started a thread on it), but it wasn't damaged or anything.  Despite all that, Amazon is still my go to for new readily available albums. Ebay and Discogs are a hit and miss as the NM grading is severely abused and often leads to disappointment. The local used record store prices are close to a new copy - at least that's been my experience in LA.

+++ all the info above plus invest at a minimum in a wet / vac record cleaner.

i frequent Discogs, rarely buy below 99% positive feedback and never below NM- on the disc. 

Enjoy the rabbit hole as Brian so aptly  said !
