I bought my TNT 3 used but VPI was always helpful. You might call them and say that you wanted to buy the plastic screws that go with the VPI Prime Signature. If they ask, say you lost them. I almost lost one of mine. My not very limber fingers dropped it on the carpet as I was trying to mount a cartridge. I was about to call them but I found it. They very likely will send them to you for free, but if not, how much can they possibly cost?
I purchased my Pass Labs XP-30 preamp and my Pass Labs XP-25 amp used, and I'm happy with both of them. The only way I can approach the high end is by buying used. My ear has exceeded my budget. Although, I inherited some money last year and was able to purchase two new Sonus Faber Olympica V speakers. I have a very revealing system now, so I can more than ever hear the difference between vinyl and digital. I can also hear when vinyl comes from a digital source. I have purchased a lot of reissues and almost all of them are from digital sources. So, even when a record has been reissued, if it's from a digital source, I will look for a used one in near mint condition. Ask Chatgbt about a reissue and it will tell you if it's from a digital source.
