I'll second what others have said, and suggest that for now you can do some good wheel truing with the wheel right on your bike, as long as you have a good eye. If you decide that you need a truing stand, the park ts-2(.2) stands are great, but there are other great options out there that will get the job done very well for MUCH less money. I built this one based on Roger Musson's plans (google his name if you're interested in checking out his wheel building e-book). It didn't take too long to build and only cost me $28 IF you include the price of the downloadable e-book. I've been extremely happy with it.
