AC power supply for Nottingham Analogue

PS Audio Premier holds the voltage quite steady at 120 or 121. Still everything sounds better after the midnight.

Thank you all for your answers.
After talking to a Nottingham Analogue salesman, I'm going to try the Pro-Ject Speed Box DS. It's a more affordable solution that is proven very good.

migueca, 

how has the project speedbox performed with your nott? I have a 294 and would like to try an affordable option but the 3 watt power draw seems low. 

Would like to no if if you have had any functional problems, excessive heat? 

Also, did you notice any subjective improvement in sound? 

If you can still find a Phoenix Engineering power supply floating around, go for it, with or without the "Roadrunner" device that allows you to lock on to platter speed.  (But do also get a Roadrunner, if you can find one.)  I'm using these with my Lenco and works quite well to pinpoint and hold 33.333 rpm.

Joegator,
Yes, it works fine with my Spacedeck. I don't notice any problem at all and I also don't notice any changes in sound. 
I bought it mainly to stabilize the speed because I will soon be moving to a place where there are some fluctuations in Power supply from the grid.
