Hey Bob, There's string makers called the Euphonon Company. You can get all kinds of strings from them in any guages. They come loose in a jet pack with no packaging. They're cheap, cheap, cheap(costwise). If I'm not mistaken they make strings for Martin, Guild, Ernie Ball, etc. I've used them for years and as a gigging musician I'm always looking to cut corners. Might want to give them a try. Here's the web address: http://www.theguitarport.com Click on the 'strings' option and the Euphonon Co. has it's price list right there. Along with all the other advice you received(all good, BTW)the alcohol and soft cloth trick will extend the string life a ton.
