Help me make a decision! Turntable overload

I have it narrowed down to the following TT's:

Rega P2 (Or maybe RP3?)
Onkyo CP 1050
Pioneer PLX 1000

I have the Pro-Ject Tube Box DS ready to rock!  
I have no problem upgrading carts - Have my eye on the Ortofon Bronze.  

Thinking my budget for the TT is $700...  I know the TT's listed are all slightly different animals, I'm all over the place, I know...
