Where are good places to buy inexpensive office furniture?
I’ve ordered office furniture from Cymax that was inexpensive. They have sites based on each brand (Bush, Bestar, etc) but it looks like you can just go to cymax.com. Here are their L-shaped desks, some look fairly modern and quite a few are under $500. I think you’ll have to put it together yourself, but based on the stores you’ve already considered, that’s probably not a big deal to you.
