it would be to your advantage to stay away from them,
electric or gas???
either one has their problems that go along with them.
the biggest disavadvantage is
1. the initial cost, you never re-coup it
2 if it breaks down , I can almost guarantee no one except maybe in Denver
is going to be able to service it quickly
3 parts can be a problem to gget quickly too
