Best CD sleeves out there


I am wondering what everyone's opinion is of the best cd sleeves on the market right now. I volunteer at my local library and I have to replace about 5000 jewel boxes with sleeves to save room...we have run out of space and we need to make the switch asap. I am interested in long time durability, ease of use, and the capacity to stick the liner notes/leaflet in the sleeve with the cd. A deejay told me he uses Tyvek sleeves...any opinions out there?

Any difference between DiscSox DJ Sleeves and Jewelsleeves? I am about to sleeve 1000+ discs...
Thanks - going the Jewelsleeve route. I don't look forward to the actual sleeving though...
i get the impression the jewelsleeves don't accomodate the tray card? and that the discsox DJ pro do?

Jewelsleeve does accomodate tray card. I can confirm this, as I just did a batch...
