Forced air systems can be zoned, but that can add significantly to the costs. If the ducts don't have and dampers in them, they can be added. balancing the airflow can help, but without zoning, may not solve the problem. If there isn't a good air return duct in the basement, add one. Trying to blow air into what amounts to a semi-sealed room is very inefficient - that's what happens if there is no return. If you run the fan continuously (not a bid deal with a variable speed fan since the default speed is quite slow), it helps. Also, if you run more heat into the basement and let the natural convection take it upstairs, it sometimes works well. If the house is tight, this won't work. I rarely close doors, so it works for me.
I also found that a high return works really well in the summer when running the a/c...it takes the hot air out from the ceiling area and recircuilates it making the whole thing more comfortable. in some houses I've been at, they extend the ductwork up the wall and have two registers; one at the top and one at the bottom. Use the lower one in the winter and the upper one in the summer.
I don't have enough experience with the various brands to recommend one over another. Some of that will depend on what is available locally, and finding an installer/maintainer you can trust.
If you aren't making much of a change, then a R&R of the old one may not save you much. Check with the installer.
