I recently saw that eMusic and iTunes both carry a Compilation called 'The Ultimate 60's Surf Classics.' There are about 100 songs on it and iTunes has it for $11.99. I found this when I was looking to buy the Strummin' Mental Series. Looks like most of the tracks on this were also on that set.
It's perfect for anybody who's been looking for some killer rare first wave sounds. There are some fantastic songs on here, and I was able to discover a bunch of bands that I'd never even heard of. Plus, any comp with Fender IV on it is automatically cool.
