I need to purchase a backup drive, and I am reluctant to pay apple prices. So I am thinking of getting a really good HDD enclosure that contains FW800 (It would be great if it had wireless acess like apple's) so I could backup photos and things fast! I could also use it to update the backup storage in the future and recover some files I have on my current dead computer. Could anyone suggest any and what is the cheapest place to buy the best?
