I have a MG50DFX (50 Watt) and sad to say it but it is not the best amp ever made. If you are looking to spend that amount rather get a Roland cube. Rather buy secondhand and get something bigger. You'll get tired of the 15w very quickly. There's a nice secondhand one in the classifieds
http://www.guitarforum.co.za/classifieds/(s)cube-60/. So for a few extra bucks you can get something a 100 times better. Good luck with your search. ?
