For what kind of Mac? That could narrow your choices.

Not to defend OWC, but this seems pretty straightforward: http://eshop.macsales.com/shop/SSD/OWC/

For example, if you have a brand new MBP with a 6G connection, then you probably want to go with a Mercury drive. If you have an older MBP, mini, etc -- then you want to look at the 3G Electra.

It's cool, I figured most responses would be promoting OWC. It's to use as an external boot drive for a 2010 iMac, in a FW 800 case. I'm already clear that I don't want anything more expensive than 3G.
