I'm too lazy to start over from square one on an instrument. Also a dilemma I faced when deciding to try it out, I noticed they pretty much only come in the key of C or D. One thing I like about the guitar is you can play in any key with it, and you can even tune it down or alternately for more options. Before I got back into guitar I tried learning recorder instead of tin whistle because you can theoretically play in any key with a recorder. I didn't stick with it though, especially when I ended up going back to guitar.
