I purchased a '12 drawer rolling cart' for $30 shipped on ebay. I see these things going for about $30 to $50 (that's including postage).. I wouldn't spend more than $30 on it but I now use one as an enlarger work table.

I can roll it into the bathroom and print, it's great. It has 12 drawers, each drawer is like 9x11x2.5" so it holds little things like filters and pens and whatnot. Mine is stuffed with just about everything I can fit in it.

My enlarger barely fits on the top of it but I like this set up, it's clean and efficient.
I'll post a picture (no digital camera at the moment) on monday if anyone is interested.
It would work well for a larger bathroom setup.
