I snagged one like that but had to rig up the power supply. I occasionally have to adjust it to keep it tweeked in but it seems to work pretty good. My biggest complaint was there were no instructions with it. There are a couple of switches/settings on it I haven't ever messed with but I have no idea what they do. Main problem I was having was when I was trying to run it and it wasn't perfectly level.
Looks to be a pretty fair price considering it comes with the power supply which would cost you around $8 shipped.
Just remember though, MADE IN CHINA!!
