I would love to help you with this but I need a little more info...
what do you already have and what you hope to achieve?
Are you looking to create simple "demos" of your songs with just a vocal and guitar?
Are you looking to create fully produced songs (drums, bass, guitar, synths, vocals etc.)
There are soooooooooo many ways you could go but it is important to define what you want to achieve (including future growth/development) to ensure you get the maximum "bang for buck"
Do you already own a PC or MAC (including IPAD) as there could be some "software" solutions that might be better for you than a standalone multi-track recorder so it might be worth posting some specs of any existing computers
The first step should be for you to detail EXACTLY what you would like to record
