AC power supply for Nottingham Analogue

I'll be more specific:
So far I've been running my Spacedeck directly from the wall, never used a AC outboard. 
But I will move to a place where the power from the grid is not very stable and I read many good reviews about the Wave Mechanic and also the Walker Audio PSUs. 
My research now as to do with the prices. Right now and for a long while I can't afford the Wave Mechanic. That's why I'm asking if there are other cheaper alternatives. 

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.

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. 

I also considered buying the Phoenix Falcon (after failing to find the Eagle, apparently discontinued and hard to get). But at normal prices, the Falcon is a bit more expensive than the Project; and I found a Project for almost half of its regular price, which became a very nice deal. And I'm happy with it. 
Let us know later about your experience with the Falcon. 

Lewm,
Yes indeed it was a learning process. When I started searching for a PSU, the first device I heard about was the Eagle - that I couldn't find anywhere. Then I turned to the Falcon, but in the meantime got this Project for almost half price. Made some inquiries to make sure that the Project would suit the Nottingham and finally bought it. 
The Nottingham motor is very low demanding (not sure if it is around 1.5W), and so far it works perfectly.
