Depends on what you want;
If you want a budget performance SSD, buy a SandForce controller SSD.
If you want an SSD that will last the longest, buy the Intel one. G3 is coming soon so I would wait.
If you want a no thrills SSD buy an SLC SSD.
oh yea, C300 is good too. .... Forgot about that one.

Wat?
If you want the fastest and most reliable SSD you buy a single layer cell SSD. OCZ used to sell alot on Newegg, I think X25-E is only SLC available on newegg. They are very expensive, 600 for like the 60 GB OCZ ones back then.
How do I know if i have SATA 3gb/s or 6
