It took some while to take in your rig fully, but dear me, you've done a very fine job there! I'm quite envious of your setup, both in terms of looks and the rather good looking trade-off between rigidity and ease of packing away the thing when space is needed for other social activities.
I do fancy your pedal setup because it's one of the things I'm not entirely happy with with my own Wheelstand at the moment.
All things considering, and factoring in the "I did this with my bare hands" feeling, I'd say it's worth every penny you spent. Very well done indeed!
Also, interesting to learn you might want to switch to PC sims (and triple monitors). Not to derail this thread, but a (relatively cheap) 3D projector has added a whole new dimension to GT5 for me and I hardly miss the triple screen setup I originally planed for.
To stay on topic: bravo! Wouldn't mind some shots of your rig "in action"!
