A few years ago I decided to buy a Brian Moore iGuitar with a USB plug built in as a novelty. It sat on my wall for a few years until I discovered its value for a direct plug in to the computer. This guitar was not all that expensive, plays extremely well and tracks spot on. I also tried to to a Roland GR-33....amazing ! FWIW I record using Cubase 6 with a MOTU firewire interface although that is not a requirement
