I have the steering wheel stand found on eBay...I've seen it mentioned a couple times in this thread. I like it quite a bit...it adjusts to fit my 6'3" frame easily, it's relatively light weight yet sturdy, and it will work with many different seat configurations.
I started out using it on my recliner which worked well, but I recently picked up an AK Rocker and now I love it even more! Now that I'm sitting down low to the ground it really feels like I'm racing a car...not a big 18-wheeler. The AK Rocker is great, very comfortable for the most part although I did need to add a little lumbar pillow behind the cover. It's pretty thin padding and after a half hour or so of racing I would start to feel it. Now I could probably race all day...
