If you want a reliable SSD go with one of the following:
Crucial M4, Intel, Samsung
If you want a Performance drive:
Corsair, OCZ, Kingston HyperX or any of the Sandforce SSDs (the Newer Gens of course)
Now as the overkill on RAID0 with performance SSDs. I don't think it's completely overkill. Depends on what you like and how much you can afford. With the prices of SSDs falling quite a bit, you can easily afford 2x120GB SSDs or even 2x90GB SSDs for a small raid setup.
I have 2x120GB Corsair Force GTs in RAID0, I have my OS, Photoshop, WoW and SC2 installed only; with still 100GB free, everything else is on my WD Caviar. If anyone plays WoW, they know it takes a while to load especially off a HDD especially if you're parked in say the middle of Stormwind or Ogrimmar with thousands of people. Let's say with my RAID0 SSDs, I load WoW within 10secs after hitting my enter key to login from the login screen. Everything loads almost instantly, it's a raid safer, if you ever get DC'ed in the middle of a raid and you can almost instantly log back in.
