I've seen the MIG50 more than this one (MIG60) but I'm not sure which one is better for the money.

I've heard these amps are great, and they're not too expensive which is why I'm considering buying one. The only problem is that they're hard to come across and this one looks like it's in nice condition. Thanks.

I've never played a Mig, but you are getting a good value by buying a used russian head - could be perfect tone for you
