I get a lot of heavy use out of my gear and the Lexar FW800 CF Reader is a pain in the ass. On one hand it's super fast, on the other, I've had to replace it twice this year because the connection to the reader goes bad.
However, my Sandisk 12-in-1 USB 2.0 multi-card reader, while a lot slower, is very dependable and durable. I've never had to replace it. It also comes in handy when it comes time to download cards from others snapshot cameras, which I do often on set.
