MIG100s on used guitar center are 799!

I see an AMPEG v4 on there WITH CAB for 700.

Right now, my gigging band is pop punk, i'm using an AMPEG R50H and an Avatar 4x12. I was planning on buying a MIG100, but at that price I can almost buy a JCM800. I know the V4 isn't going to have that crunch channel but it has a really nice loud clean tone that you can build off of.

But really, I feel like the MIGs are great amps, but they were great because they were "cheap" now that they're going for almost $1000 what's the point?
