I've used some of their controls and I have to say that the "feel" so to speak just wasn't the same as the real deal. I really don't know how to explain it, but the buttons didn't "click right" if that makes any sense. The joy sticks were a little better but not perfect. However, if you're looking to save money on a first project as you said, then I'd go with them. The products may be a little flimsier than others, but no need to spend a bundle on a first project that you may (or may not) make some pretty big mistakes on. Besides, you get used to the feel after a while. Plus, it's still loads of fun and you can always upgrade to more expensive (and complicated-to-install) controls later after you get better at it or save more money.
FatTrucker is right to buy where he does, Ultimarc and Happ products have the best feel. IMHO.
