If I could give you one tip,
don't waste your time with the low end stuff. I'd select a few reasonably prices cards and save towards them. Having 100-200 $1 cards is nice of course, but think of the postage spent on all that. You could've probably saved and had an awesome $350 Exquisite auto of him (possibly an auto patch?). Or a sweet refractor maybe (not too sure how high Rose's cards go).
I always find if I buy quality cards ($30 - $50 range) they at least hold their value, sometimes go up a touch, then I sell them (even if pc unfortunately) to get something VERY nice. It's kind of another way of saving + collecting at the same time.
I had 100 Tim Duncans, but they were nowhere near as nice to look at as my Playmakers Theatre T.D.
