Abt Electronics

Abt Electronics have been going since 1936 so I would imagine they have a solid history and know what they are talking about.

Their website is pretty well laid out with a pleasing blue and white header and 3 column layout with help, promotions and product search easily available.

Some example pricing from the USB card section are as follows:

• Sony 1 GB Memory Stick PRO Duo Media - $ 34.00
• Transcend 2GB Compact Flash Card - $ 47.00
• Olympus xD M2GB 2GB xD-Picture Card - $ 37.00
• Transcend 2GB Secure Digital (SD) Card - $ 19.00

And these also all come with free shipping so it's pretty competitive.

Their search is easy to use, customer service is easy to find and they seem to stock electronics of most types from digital camera technology to cell phones.
