I'm definitely gonna spring for 'em, cause the only one I still own is Babylon. I used to have all of 'em too, but have lost them over the years.
I did too, at one point or another, but my collection has thinned out a fair bit through the years from lending them out and not getting them back, then promptly forgetting who they were lent to in the first place. I've probably only got about 3 left, so this is pretty good news.
I just wish I could figure out where I put that Billy and the Boingers floppy vinyl. :'(
