Samsung has the best SSD's out right now. I own the 250GB Samsung 840 and it only cost me 179.99. Comparing that to the 229.99 some other drives cost and that's a steal. And this drive comes close to the top in performance even though it uses different nand. It's close to the 840pro in reads.
I also own the Crucial m4 256GB, Crucial m4 64GB mSATA, and the Kingston HyperX 120GB. They are all some good reliable drives. But the Samsung performs the best out of all the benchmarks. I have a feeling the Crucial's will last the longest though, that's why I have it in the system I use the most. Crucial is by far the most trusted name brand out there, even better than Samsung. But you can't beat Samsung's prices, and if you need a laptop SSD, then Samsung is the most power efficient there is.
As far as pricing, if you can't find a 120GB 840 for 89.99, then look elsewhere. If your looking for a 250GB, try to find it for 179.99 or look elsewhere. You should be able to find those prices fairly easily as I did, and like I said, if you don't get that price then try a different website.
