Kurt, the Schumacher box at Wal-Mart is very inexpensive for all that it does (there's a charge circuit in there too) and has a 22ah battery in it for $130.
Other than that these boxes are ugly as sin, they're probably a good place for most people to start. I'd ask Schertler if they have any caveats about your using a modified sine inverter, just to be completely assured.
