Anyways, I'm about to build my own, I think, because I currently have a HUGE round table for my G27. The main problems are...well, everything. The whole table is terrible, so terrible in fact, that I had to use some flooring, and some crown moulding (what's the word if it goes at the bottom?) To hold the wheel and shifter in place.
Oh, and there's a huge wooden table leg (one, in the center) and I'm 6'3" or 4". I need leg space, but, have none. Sitting at my G27 table was like sitting in the first of our three Hyundai Accents (a '95 model... Which had 2 feet of leg room.) Thankfully, at least, there were no airbags, because my knees were against the dashboard.

Slightly off topic, but, you get the idea about my table now.
Anyways, I'll give you feedback, if you need.
