Which SSD is best?

I am getting a SSD for christmas. I want to hear your guys opinion on which SSD is right for me.
My system spec: Q6600@3.0ghz
4gb
850w OCZ ps
8800gt
Win 7 Pro 64

I recently purchased the new Kingston 40gb SSD with the intel controller for $85. I'm starting to think I will give that SSD to
my brother for his i5 750 build on Christmas.

My price range is $250-300. The cheaper the better tho.

I had my mind set on the Intel X-25M 80gb but I'm not sure now because of the slow write times.
Intel X25-M Mainstream SSDSA2M80G2R5 ~$250 on amazon

OCZ Vertex Turbo OCZSSD2-1VTXT60G 2.5" 60GB $250

Kingston SSDNow V-Series 128gb $284 (doesn't seem faster than conventional drive)

Corsair P128 $370 (over budget..might be able to find better deal)

I have not received the 40gb Kingston as it is still in the mail. Would upgrading to one of these drives be worth it? Is the Vertex
drive with 20 less gb better than the Intel? I wish I could afford the 120gb Vertex or Intel 160gb but those drives are out of the budget range.

Another main concern is trim support. Since only OCZ and Intel support it right now that also factors into my decision. I hope Kingston releases their trim support soon.

Thanks everyone in advance.
