It depends what kind of skier you are, and what your expectations are.
If you're looking for the cheapest to live (not to ski), best overall skiing between powder/backcountry and park and variety of terrain, go to SLC. This is assuming you don't do lots of drugs, raise a lot of trouble, or expect to nail a lot of women. Thing about women though is if you move to a mountain town and expect to get lots of tail, you're delusional. You probably have better odds in a big city--even if it's Salt Lake City. You can get a season pass to a single resort for $600-$1000 depending on your situation, or 2700 for the silver pass which is good for every major resort in Utah.
If you ski mostly park and want good night life and chances to do lots of drugs, go to Breck but it's pretty damn expensive to live there but an epic pass is only about $700 for numerous resorts. You'll be slaving away with a job much of the time to afford it. Summit county is pretty garbage for powder most of the time because they don't get it often, and when they do the Denver folk jam the interstate and often it's pretty damn tracked out by 10am. Only good long lasting worthwhile powder I've had was last year when we had all that late season snow and everybody back in the city had already called the season quits.
If you're talking Aspen which is pretty remote, why not consider Telluride as well?
If you chose SLC, you can hit me up. I'm talking to a landlord now who has two bedrooms available in a house, one is 325 and one is 375/month with utilities included he says.
