A couple of my friends who have been playing for years both recommended Kyser so that's what I bought. I'm a beginner (only 3 months in) but I find that it gets in my way and makes it harder for me to fret some of the chords. I'd like to find a smaller one but I'm not sure what to look for either... but I confess that I haven't put much research into it at this point.

I look forward to hearing what you decide on and seeing what other people recommend.
