Help me Buy an LP-12

I have had a Rega P3 w/ Elys for a couple years and Im bored to tears with its sound. Its nice and non offensive but does not excite me. It cant even begin to hang with my Meridian digital rig. So, I want an Lp-12. I dont really understand all of the upgrades and the different models. Does Sondek refer to the power supply or are all Lp-12's sondeks? What I need is an experienced LP-12 user who can help me put together a starter Lp-12 set( table, arm, power supply, cartridge etc.) That I can look for used. What are some quirks, or certain years, models I would want or to avoid etc. Any advice would be very much appreciated.
