"I will put that extra money I saved from not buying disc-o-file record sleeves toward a more important item that protects the investment I made in records...and that is to buy my expert stylus company diamond styli directly from Kurt Nauck. Now that is a great and important investment." AMEN, brother!! Couldn't agree more. And in spite of my claim that Disc-O-File sleeves are better than oxygen, probably 2/3 of my collection are housed in Bags Unlimited sleeves. Granted, I bought them way before Nauck's sleeves came out, but I haven't replaced them, either. "Does anyone have an opinion on APSCO's sleeves? I've always been pretty satisfied with them, but perhaps I'm just not sophisticated enough to know any better. How, exactly, are they different from BagsUnlimited's, or anyone else's? This is a serious question." I've wondered this myself. Anyone? r.
