I don't use my floppy drive anymore either, and the next system I am building will have no floppy drive. You don't need to use the MaxBlast4 bootable floppy either, you can get the ultimate boot cd (www.ultimatebootcd.com
) which has MaxBlast 3 on it. That should be fine. If you need MaxBlast 4, you can make it into a bootable cd using nero I believe.
if you still want a floppy, any brand should do. you can pick up one at compusa, or get a cheap $8 one online. the floppy drive isn't a critical part, and you won't experience much downtime if it fails.
