I agree with all of the above, but be careful - when I was learning I ruined a couple of valuable instruments - they were so cheap I didn't know what I had got. I've seen a couple of other cases where this has happened. On the other hand, I once walked into a repairman's shop and found a guitar for sale that I had repaired. I'd fixed the top crack so well he didn't know it was there - biggest compliment I could ever get!
