You're probably not going to find anything worth having that's under 10 gigs. The least expensive drives are Quantum, Fujitsu, and Samsung, but I cannot in good conscience recommend any of those brands cheaper drives to you, because they are not worth having. Your best bet would probably be a 20 gig drive, either Maxtor or Western Digital. They're about $67 plus shipping. You can find whatever you're looking for at www.pricewatch.com Good luck!
