Yeah i know how you feel man, it pours from me, and my poor fretboard gets it all! i got them from a local shop, and prices vary, i mean they are quite expensive as far as strings go, but personally i think they are WELL worth the money!

Here's a link to an online shop (where i think do the cheapest strings)

thats to some Custom lights, for $9.95 (im assuming your in the USA > sorry if im wrong!)
