Great books and congratulations on inching ever closer...
I'm surprised that you still needed issue 77, as it's one that I've seen more often than many other early issues. Of course, the prices some sellers are asking for run fillers still verge on the obnoxious. I've been watching Dells for years and many listings on the Bay and even MCS still make me scratch my head (for example, a later mid-grade Mother Goose for 10x guide). I still grab an occasional Four Color here and there and even at $9.99, when shipping and/or sales tax is included, you have $20 invested in a run-filler that your heirs would be hard-pressed to get two or three bucks for. I imagine, however, when you're as close as you are to your goal, $20 is a screaming bargain for books you still need!
