Hi guys and gal! So I've got this chance to score some "new in wrapper" type III ferro chrome cassettes. I think I can get them for a killer price,like .50¢ each! Any info on this type of tape would be greatly appreciated. I have experience with type I's,II's and IV's. Each have their merritt's, just never ran into the ferro chromes before. Most of my boxes don't even have a setting for them. I see that they go for quite a bit on epay. I guess they are very rare. Well I've babbled on for long enough,whadda ya think?
