I know that if money wasn't an issue, I'd get sucked into the high grade, CGC realm pretty easy. But, it's still a hobby for me and one that I don't spend huge amounts on. (Now that house is paid off, maybe I can convince my wife that the collection deserves more moola? ) I try never to use a credit card for comic purchases, especially at shows as it would be too tempting. I tend to save up for 6 months for the Motor City Show and bring cash. I'm excited for this next one as I've saved up $1000.00 which is about double what I usually bring. Of course, I still like to get a lot of books for the buck also.
