I have an
ESP F-50 guitar and a
Spider III 15 watt amp.
I've never bought anything from Rondo Music, but I've heard great things about it, so if you decide to get something from that site, you're pretty much guaranteed to love it.
In addition to the Spider III series and
Micro Cubes that Matt mentioned, I've also heard good things about
Transtube. Keep in mind that all three of these models are all practice amps though.
