Unless you go to Ikea and get an 8' dining room table, this is the least expensive solution that I am aware of, that will give you 8' of space, with some rack mount ability. I have recently become aware of Martin & Ziegler desks, and they are certainly much nicer than the low end Middle Atlantic MDV series, but ultimately it costs more money. And the Raxxess series (another cheap video furniture series) is still not as cheap and functional as the Middle Atlantic MDV.
Again, you can do nothing other than get an Ikea 8' dining room table (8' desktop and 2 Ikea saw horses), and a Raxxess or Middle Atlantic skeleton rack, and do this even cheaper.
I actually like the Ikea idea. I think I may look into that. As always I will continue to check the craigslist listings. Like Jason, I have gotten lucky a few times with craigslist. Thanks Bob and Jason.
