Any of the Fusion RC range are very good. I personally have the
Paladin L120, which is really simple to use, can charge at up to 10A, and has 10 battery memories. It will only run off 12V DC though, so you may need to grab a power supply too. It does come with a balancer though.
They have recently released
this though, a 90W (AC) or 120W (DC) charger, that'll charge up to 6S at up to 8A. You'll be able to charge most Lipos at a rate approaching 2C, and it has a built in balancer too. It is more expensive than the Etronix, but it is also quite a lot better.
