I've been looking at chargers myself and I'm trying to decide wether to buy a decent charger like the Integy 16x5 v6 or go all out and spend more money on a Pro Trak, knowing I'll never need a new charger, just the occasional upgrade.
The Pro Trak is winning me over the more I read about it, it's easily the most regularly updated charger, not because it needs improving a lot, just because people ask for features and the guy that makes them then adds any sensible ideas. The current version charges up to 14amps, don't think anyone will want hhigher than that at the moment
and it discharges at upto 20amps. One of the best features are the individual clips you can use to moniter each cell while charging/discharging while still built into a pack, you can even use this connected to a pc and see a graph of each cells performance and get a rating of how matched they are, you can use it to match new individual cells too. There are some good extras you can buy too, like a temperature detecting tray that has sensors in four places and when hooked up will allow you to charge to a temperature of your choice rather than a normal peak. You can run in motors at upto 6v too.
The Victor charger sounds very good but I'd rather have something I know I can get repaired, being in the UK the Pro Trak will be the quickest to get serviced out of all chargers for me.
The Turbo 35 GFX seems a nice charger but overpriced, I don't see any major features it has that the Pro Trak doesn't.
