I have a TEAC floppy in my new rig and it works just dandy. There's also a TEAC in my Dell, which saw quite a bit of use over the year that I've had it. I paid $30 for mine, but I've seen it for $20. Honestly, a floppy is a floppy. Brand doesn't matter at all. Buy a new one and it'll last you forever. You'll probably blow up everything in your system (figuratively, not literally, I hope!) before the floppy dies. My friend has a 286DX from like, 1903 or some very old time (joke) and the floppy still works. Get the cheapest NEW floppy you can find.
