If you are recording on your PC I would go with the Roland Micro cube. I have one I use for that very purpose. I just run my line out straight to my sound card and it works great. Very portable, runs on six AA's or the power cord that comes with it. It has several different COSM models of various amps also has chorus, reverb, and other effects. Very versatile and souds great! Don't let it's small size fool you. This thing gets loud. Produces any tone you want from clean to heavy distortion! Check it out on Rolands website. I think you can get one on EBAY for around 100 bones. I also own a B52 halfstack with the AT100 head and I would rather record with my micro cube. I own a GNX4 too and yeah they are awesome, but one will set you back about 350 bones and it's not an amp. Also, check out Harmony Central's website. They have reviews of tons of amps.
