Power Amp Advice

[Purple Reign]

I'm looking into buying an Axe Fx Ultra on ebay and I was wondering what kind of solid state power amp I should get. Here are my specs

-at least 800 watts of headroom
-smaller and lighter
-reliable
-in the ballpark of $400-$800

Thanks!

Crown XLS 1000 or the 2000 can be had new for that budget.
