The SanDisk ImageMate 12-in-1 is one of the faster USB readers out there. The performance test I found put it was being equal to the SanDisk Extreme USB reader for CF/SD performance, plus it supports Memory Stick, xD, and other formats. In general its one of the best performing readers. It's generally over $30 plus shipping (or $35 at Staples and the like). More expensive than no-name or harder to find brands but excellent performance and can be obtained at BM stores.

Right now it is $26.99 at Best Buy, in stock (Link Here). Not sure how long the sale lasts.

If you have a Circuit City nearby, print out the BB page and price match it to get it for $25.69 (10% off difference). I had no problems doing this.
