I recently replaced my entire power center/distribution with one of these:

Charge wizard built it, under $200, plenty of circuits left over... everything works better. Seriously. If I was going to run AC, I used to HAVE to be plugged into 30 amp service. After the new converter, I got stuck on a hot summer day on a 20 amp service and decided to run it "while I could"... it never tripped the breaker... never had a problem.
Had I known how easy it was going to be or much of a difference it was going to make, I would never have put it off for years... and years.
