Ah, don't sell yourself short though. One thing I'm not sure I've successfully stated anywhere is that price isn't always an indicator of great yarns. Price can be an indicator, but how it feels, how it wears, how it is spun also play a huge roll.
Yarn that splits or pills, or stretches (when it shouldn't) can make a finished product look bad, wear poorly and make you miserable.
Enough said.
I, too, try to hit LYS's when I travel and use the yarn as a souvenir. Very fun to have a hobby. When I travel I also look for used book stores to see if I can find any hard to find knitting books.
