Yes, Crucial is the other company I recommend. The Crucial m4 is a popular ssd. This year Crucial has been leading the pack with some really good price reductions. Crucial is able to do that because their parent company is Micron, a major manufacturer of NAND flash memory used in ssd's and other chips.
I maintain the ssd database listed in the sticky at the very top opf this forum section. Here is the link:http://www.johnnylucky.org/data-storage/ssd-database.html
