I'm thinking of getting either one and I don't know which one, so I figure I'll start a fight to get help and an answer. Reasons would be great but a post vote is more than helpful.
We are authorized dealers of both. Both are such solid amps and the q3500 is on an unbelievable sales price right now. Let us know if you need any assistance.
There is a 3800 on here for $540 that is in fantastic commercial. That's what I'd get. I like the look more than the 3500 and it's for a steal price used.
