There are MANY good qaulity chargers and cyclers out there, many of them combine discharging with re-charging (thus the name "cycler").

The Schultz is a top line product, so is the Super Nova (Dymond and FMA are each licensed to make them), and there are a number of other good quality units on the market.

A former club president has the Sirius equipment, and he said it's no better than others he's owned. Personally I have a Super Nova, it automatically discharges at the proper rate for the pack, then recharges at 1C. (It reads the pack to determine proper voltage for both discharging and charging, and it's a "Peak Detection" charger for NiCD's and NiMH's. You do not HAVE to discharge first, I use it often to quick charge on the way to the field. (15 to 20 minutes for an average flight pack.) So it's truly a "plug it in and forget it" unit.

It can also be set manually for special applications (like if you want to charge a pack at 3C), and it has the capacity to charge up to a 24 cell pack if you fly electrics.
