Hi, I would recommend using a PC, you need as fast a processor in it as possible, running windows xp as vista is still a bit crap for music, 2gb of memory, a separate graphics card (not built into the motherboard) , a decent set of powered monitor speakers (M-Audio, Edirol minimum 100) then buy any version of Native Instruments Guitar Rig 3 you can get your hands on....You will not believe your ears. Go for the rig kontrol version if you can afford it, otherwise go for one of the cheaper setups, you will have the best sound and recording setup available on the planet and your recordings and live sound will be astonishing. DO NOT go for an ancient tape/cassette system - you will suffer NOISE. This is the future and if you ignore it you are missing out in my opinion. I am expecting criticism.....bring it on
