Look for a Powervar 12amp or a Oneac, either is infinitely better than the two you are considering (sorry, I owned them both and sold them)...and you can probably purchase them much cheaper.
A member here sells the big Powervar. I bought one from him and recommend his product and service. I also bought an 8amp Oneac on EBay for $25 (shipping included) Have had no issues either with sound or workmanship.
Good luck in your search.
