Was looking for a link to current-version of the "aircraft carrier" desk from BIF that I once had. It qualifies as "deep and wide" (in spades) but doesn't qualify as affordable. The beast had a humongous full width/depth drafting drawer under the work surface. That was more than 20 years ago, so I'm sure no longer made. It had a nice assembly system with cam-locks.
But since the pictures being posted here are nowhere near what I would call "deep and wide", this one looks pretty interesting, similar size to those posted, and has some storage:

Or, a bit bigger:

says "available in other finishes" but does not specify. I would assume to include white!
Or browse the broader selection of desks, some pretty nice designs here:

FWIW, I currently use a frosted-glass-top "kidney-shaped" desk from Ikea. I like that it has a big well-hidden cable tray (thus frosted glass!) and adjustable height. (Not instantly adjustable, just adjustable during setup to suit one person's height need.)
Edit: I guess BDi is a spin-off from BiF that now has the office furniture lines, while BiF is refocused on home furnishings.

Lordy, I guess I had that desk like 35 years ago. I had it shipped to CA from MI. I had worked for a company that did drafting services for the auto industry. They were able to arrange a substantial discount. I used that desk for 25 years, until I moved to a place where it was just too big.
Trivia: I believe BiF stands for Borneo International Furniture. Originally, the wood all came from Borneo. They were flat-packing way before we had Ikea in the U.S.
