I'll make a recommendation as you have researched the contenders. Buy the one you like used and if it isn't what you like you can sell it with little risk. I've done this more times than I care to admit. Not really very risky when buying from members in good standing. It keeps those UPS/fedex drivers busy.
You can't go wrong with any of the amps recommended so far.
