I was in your position X years ago having been fiddling with my guitar and teaching myself for 5 or 6 years..well,when i got to uni i met some guys who just floored me, these were students too, after that i can tell you i took lessons and after 5 or 6 lessons i was ready to play,could jam a lot better and had the rhythm skills (heavilly into J. B./Jimmy Nolen at the time) polished up to play in public,which i would never have done otherwise.
If you get a good teacher it can be fun and, often, if you ask "how do they do that bit" you'll be surprised how simple it is, a good teacher can show you how to "fake" hard bits too - that is to find a way of getting round a difficult passage to play it using easier fingerings.
Cheers.
Accuracy,you say? hmm interesting concept..
