best "entry level" audiophile TT?


I'm looking to replace the relatively crappy turntabel I'm using right now. Everyone says Rega (p3 or p2?). I've also been impressed with the Pro-Ject RM-5, Dual CS 455 Gold, and the Music Hall MMF-5 turntables. Any thoughts? any additions to the list? What are key issues / questions to be addressed in finding the best turntable for me?

Question about Dennensen platforms:

I have three Dennensen air suspension platform pistons

Do you have a link or any information about these isolation devices?
+++ The KAB mods take it [SL1200] to the $5K performance level with much less than that.+++

Really? And which $5000 tables my that be? Teres perhaps? Galabier? Avid? Oracle? ClearAudio? Michell?
Sota?

Tell me something psychic, have you ever even heard a $5K table? I have heard a SL1200 and it sound nothing like a $5K table. Doesn't even sound like $500 table.

Hey Guys, listening is SUBJECTIVE. How can you claim to know how good or bad a table sounded to someone else? Some like the sound of one table, others don't. Period. No claim of OBJECTIVE superiority can be sustained or substantiated.

Myself, I'm thrilled to death by the sound of my distinctly un-audiophile Yamaha YP-D8 DD table, unmodded, playing my Empire EDR.9 vintage cart. So my $400 rig (including cart) meets MY needs just fine. Will it meet anyone else's -- no way to predict.
thanks for the responses - quite helpful. I guess the price range is sub-1,000. I'm looking for solid quality, good sound - not sheer audio bliss. I, at least as of yet, mainly rely on other sources for music, and only have 40 records. I'm fairly new to audiophilia, and just bought my McIntosh MA6900 integrated, anticables / IC's, and vienna acoustic bach's - so I'm still recovering from the cost of all that while still looking for a TT.
And not to open up a new can of worms, but what /who / how much should I look for in terms of vibration isolation?
