Tough question, since we (and probably you as well) have no real idea about how you will actually use it. Traditionally there are three categories of rig - vacation, snowbird and fulltimer. I see no real difference between Snowbird and Fulltimer, but vacation class rigs are built for much lighter use than the other two. In particular, cabinetry and furnishings are made with lesser materials and craftsmanship and things like insulation are usually of lesser quality as well. Price is a fair indicater of which class you are looking at - the vacation rigs are notably cheaper.
I recomend buying an older high-end rig rather than a newer one of a lesser brand. I think you get more for your money that way. However, the size range you are looking at is not well populated with high end models, since they are typically 34 feet and up. Class A's start at about 26 feet but most are quite a bit larger. And depending on you trravel plans, you may want to reconsider the size.
I would recommend that you look at Holiday Rambler, Monaco, Country Coach, older Safari & Beavers, and the Newmar brands (Dutch Star, Kountry Star, Mountainaire). That is not to say that others are not acceptable, though. Our first motorhome was a Fleetwood Southwind and it served us well and its brethren (Pace Arrow & Bounder) are equally good. Winnebago makes a number of nice rigs, as does Georgia Boy Manufacturing. All depends on your wants & needs and your budget.
Personaly I steer away from Coachman & Damon, but others have had good results from tem.
