Ikea (in the UK at least) used to do a great fixed standing desk with piles of useful shelf space above and below, but I think it is now discontinued. I was lucky enough to get one for home free from a colleague who moved house and it didn't fit in their new arrangement in the new place.
A quick search here shows small standing height units for as little as 250UKP including VAT and motorised ones for ~500UKP - so I expect you'll find some fixed height examples available in your state in the $250 range (assuming that prices follow the 1UKP->1USD pattern seen in what I pay for electronics and similar goods rather than the actual exchange rate which is currently closer to 1UKP->1.6USD - that may be an ill-informed assumption).
Another option for home if you have the skills (or friends that do!) is to make one. Before I got the free desk we were going to take the tools to breakfast bar furniture (which a friend had going spare after some renovations and which legs of the right sort of height) and install it in that corner of the home office.
