Standard driers are 27 inches so if they will fit I don't see a reason to limit your self to compact models. Most of the compacts are 5 cf or so and designed to be stacked over a 24 inch washer. in any case you want To be sure that if you get a compact it's not a 120v one or it will take ages to dry. Roper and Hotpoint are both made by GE, the Amana will be made by Whirlpool. My parents and bother both have GE driers and have had good luck with them i've never had a Whirlpool drier.

Roper is another Whirlpool brand, not GE.

GE has a nice 24"w dryer now (this one), as does Bosch. GE also has some less expensive, stripped-down 24" dryers, some with the controls below the door for easy reach when stacked over a washer. IIRC, these don't have a moisture sensor so the automatic timer doesn't work all that well. LG has the largest capacity 24" dryer I'm aware of, but I think it's only available as a ventless (condensation) dryer (as are the Bosch and GE). Miele is high-quality, high-price. Asko is decent. Whirlpool's cheap one (with the lint filter in the back) is awful; they also have another (with the glass door & stainless steel drum) that's completely different, made in one of their overseas plants, that's somewhat better and still affordable. If a 27" dryer will fit, Frigidaire makes some with front controls that are the smallest 27"w dryers available, and are fairly inexpensive).

I also have an old GE dryer which has the same timer problem. It shuts off just before the cool-down period is supposed to start, which is the last 10 minutes or so.
