Heck man, a few pieces of 1x3 lumber, some fiberglass screen, and a few staples is all you need to build a drying screen. All of it comes from Home Depot. Bet you don't spend $30 and you have enough to make several in the size you need.
In a pinch just the screen is purchased, stretch out the screen between two chairs with books on the screen and you have it. That's what I did in college and it works fine. The screens don't have to be stretched taunt on frames, that comes later when you have a permanent darkroom and some of that stuff they call money.

Good luck,
Curt
