I'm eventually going to be setting up a DIY AIO 40 breeder and I'm kind of over the whole pre-fab stand thing myself - and I really don't trust my skills in making something different / nice / sturdy.
Anyway - we still have our daughter's changing table / dresser that's in excellent shape (she's 16 now), but it's a mahogany / cherry color, which doesn't match our decor at all - which actually makes it look like it fits in that way. All solid wood, built heavy duty. It took some time but I convinced my wife to let me use it for a stand. It's the perfect size - 18-1/2" wide x 48" long. It has 3 drawers on the left side and a small cabinet on the right side. It's going to be sumpless so I'll just put a top-off container in the cabinet area.
