So I'm in need for a dual channel charger for usgt racing. I'm going through this thread... but I've seen a few posts from frustrated users. High level and getting to the point: Is this charger worth it? Based on the price and features, it's almost too good of a deal not to give it a shot... I don't really have much of a plan to charge/discharge at 40amps as an advantage for my racing program, USGT / 17.5 are the classes I would be running... I have heard that many/most of the fast guys in these classes in my area are doing this. I have a long way to go where any advantages of doing that are the deciding factor in how I would place.

That alone puts me off from getting a cheaper charger with a 15amp charge limit. So... question still stands on should I roll the dice on this with a DIY power supply or is it problematic enough to make it worth spending 3x as much for the same capability.
