Hey guys! So my bday is coming up in a few days, and I figured I'd finally splurge for a nice SSD (let's call it a budget of up to $250-275, for 240GB+). As it's my first SSD, I'm done tons of reading up on specs and reviews, but I'm still stuck trying to make a decision.

Here's what I'm currently looking at:

Thoughts?

Do you guys have any SSD suggestions? Anything you've bought and regretted it later?

NOTE: Since I know some SSDs play differently with various hardware, here's my current desktop setup:
ASRock 770 Extreme AM3 AMD 770 SATA 6Gb/s
RaidMax Hybrid 730W ATX12V
AMD Athlon II X4 635 2.9GHz Quad-Core
2x G.Skill Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 1600
HIS Radeon HD 6870 1GB 256-bit GDDR5
500GB 7200RPM SATA 3.0Gb/s HDD

Out of those 4, I would choose the Mushkin Enhanced Chronos Deluxe.
It's one I usually suggest. It's a good reliable model.
