Query: You can probably find better for your money

The controller itself is good, but the documentation is poor and pretty confusing. The manual is on the cd-rom that comes with it, but it is hidden in a .html document a few folders in. And it took me a couple of hours just to figure out which driver I needed to download from the website (they probably could have put the driver(s) right on the cd-rom).There are many programmable buttons though, and if you're much better at this stuff (or much more patient), its probably a good deal.
