In my opinion, for folks who live in the eastern US, a Wyndham timeshare deed---purchased resale at a resort with an owner-controlled board and reasonable fees---is one of the very best bargains in timeshare.
Wyndham's system is quite extensive, with some very nice resorts at good to great locations. The units are not ultra-luxurious in the way that a Hilton or some of the better Marriotts might be, but they are well-equipped, very comfortable, and tend to carry lower annual fees than resorts in those systems do, as well. Wyndham is a system that you would buy to use, not buy to trade---the better inventory is kept for owners, rather than given to exchange companies, and as a result trade power is mediocre at best. But, when used internally, the system delivers solid value. There are a number of nuisance fees, but with a modest amount of planning, those are easy to avoid. And, if you pay one here or there, it's still no great hardship, as the overall ownership costs are still very modest.
It's worth looking at their directory---ignore the Affiliate resorts, as they have little actual inventory---to see if the locations/resorts are of interest.

The other main players in the "mini-system" game are Bluegreen and Worldmark. Worldmark seems to concentrate more in the western US. Bluegreen has a nice portfolio as well, with a few locations that the others don't serve. As I mentioned, we just got back from Mountain Run, a Bluegreen resort, and I really liked it. Maureen thought the unit itself was a small notch below most of the Wyndhams we've visited, but this is a minor quibble. It was reasonably well-equpped, well-maintained, and the resort staff was very service-oriented.
We are from Montreal, Canada, so in essence , there is no resort in particular that we will be visiting on a regular basis. Yes, we want to go to and visit different parts of the states but we would actually like to trade for Caribbean, Mexico and Europe destinations.
Do you have any suggestions of which companie might be good for us
