Title pretty much says it all. I picked up a 5150 III 100 watt recently for an absolutely ridiculous price of $500. I was really planning on flipping it for a quick profit as I already have a 6505+ and have owned a 50W 5150 III before, but holy shit, this thing just does it for me. Someone about 1.5 hours from me offered me their 5150 II stealth for $1350, which seems like a good deal as well, but I am hesitant as I don't know that the stealth would be worth the extra investment over the regular model. I'm not missing the resonance knobs on the 100 watt as I can get the low end dialed in just fine on all 3 channels. And with as much as I love the 100 watt, I'm not sure the stealth is going to be able to do anything better vs just being a little different. Can anyone chime in with experience here?
