Thanx Tony & Jason.. I'm purchasing the ESI v.3 software which I think/hope will lessen the risk of the Syquest larger capacity drives not working.. Right now I'm leaning towards the Sparq SCSI *comes out this month for MAC*, due to the outrageously cheap cartridge prices, but if the Syjet carts come down in price then I'll go for that.. Thanx alot for your quick responses.. Appreciate it..
