Would the Happ Driving USB game control interface be a good choice for a driving cab I am putting together, it looks pretty good from what I have seen & i get a real good price on these...
I think the price has been the stopping point for most people for this product. I heard of others using one of the versions (don't remember which one) and being happy with it, but with all the lower priced interfaces out there, it's not often.
If you can get a real good price ($30-$40), I'd say go for it (and let us know how well it goes

). If "good" means $99 or up, I'd suggest go for the GGG, Ultimarc, or AKI interfaces. If you use the mouse/trackball part of the interface, ~$60 is a pretty good price (analog interface + mouse interface + digital interface).
But I've never used one, so grain of salt.
