Rega TT PSU..... one or two buttons ?


I'm thinking of buying the TT PSU as an upgrade for my Rega P3-24/Exact 2 front end. I've seen different photos on the web, and it seems as if there are two versions of this unit. One has one button (33 1/3 - 45 RPM), and the other has two buttons (Power and 33 1/3 - 45 RPM). Is there a difference ? Are there actually two versions of the TT PSU available ?
Also, what are the thoughts from those of you who have the TT PSU ? Is it a significant upgrade ? Thanks a lot.

Cjnolan, I am having a tough time deciding between the basic P3-24 and one with the TT PSU and would appreciate if you can briefly describe what sort of differences have you heard. I don't mind if the improvements were subtle as long as they are noticeable but it would be disconcerting if I cannot hear any difference with the TT PSU on board.

On a separate matter, how would the P3-24 with TT PSU compare to the basic P5 without the TT PSU?
Thanks for the response Miner42. Your response has somehow increased my chances of ending up with the P5 although the P3-24 with TT PSU was initially in my shortlist.
