I have a Porter Cable, and it's worked OK for the last eight years. Back in January, Lowe's was clearing them out for cheap. Of course, you would have needed to buy pads and whatnot. Doubt that any cheap ones are left.
The packages at Autopia are worth looking into, and their service is like a lightning bolt.
The Ultimate Detailing Machine is up and running. From the people who have used it, it appears to be an improved version of the Porter Cable.
If I had no machine myself, and were shopping, I would check out the UDM on this site, and likely drag out the credit card.
