Well my vote would have to go with mixcraft, its cheap, around $74,(52 quid) you can get a free 14 day trial with no limitation and you dont have to be a rocket scientist to work it. Im using the 14 days trial version at mo and im loving it, it even comes with something called shred amp simulator that makes your guitar sound great.
Im not the best guitarist in the world but this is something i did today
