I use Crest (as well as Crown and other) power amps in my PA and bass guitar rigs. They've been on the road, fell off of trucks, and over/under volted more times than I'd like to think about, and still chug along quite well. They'll be overbuilt and should do wonders for whatever application you're looking to use them for.
I don't know that particular model, so I can't comment on price.
Edit:
My favorite power amp brand though, is QSC. I suggest taking a look into them as well, if possible.
