The Intel SSD's are still amongst the best. Then there's the ones based on the Indilinx chipset like the OCZ Vertex or the ones based on the Sandforce chipset (like OCZ Vertex 2). Avoid all others.

Also keep in mind: if you clone a regular HD to an SSD, almost certain your SSD drive's partitions will not be aligned. Make sure to align them properly before continuing to use it. Performance will be degraded immensely if you don't.
