I've got a crate powerblock that I love, it's portable, simple, flexible, loud, and sounds great through my cab, a custom made with 15" speaker. I'm still not sure why they stopped making them because as far as I can tell there's nothing else quite like it on the market, and I've read lots of other praise for them.

I would really love to see something similar available, maybe with similar features but higher build quality. Does anyone know if any companies manufacture anything like this? I have read rumours of Crate building a powerblock II, but I've not idea if there's any truth to this at all!
