I bought the Lexicon Alpha to record music onto my computer as a complete beginner, and I must say it is perfect in this situation. It has inputs for electric instruments, microphone and external music players. It comes with a USB connector to the computer, and so doesn't need any power supply, and most importantly from my point of view, it comes with a version of Cubase software - albeit a toned down version with only 8 tracks and limited number of MP3s you can create - which allows you to get going straight away (as long as you've got a microphone and the instruments!). The manual provides good, clear instructions to get started, and I must admit I have no complaints whatsoever about the Lexicon Alpha. I thoroughly recommend it!
