I have been using an Intel X25-M SSD 80Gb for the past 2 years now, have upgraded the firmware twice since I bought it. Actually haven't had a single issue with it so far, touchwood, I know they're not top of the line SSD's with the kind of speeds that one might want , but they are a lot faster than HDDs. So I think I could vouch for one.
The new SSDs seem a lot less reliable and I wonder why, because the first gen SSDs were nearly all good from OCZ, Intel & Corsair. What is surprising is that as they have gone on and tried to make a good product even better, it all gone bad.
I would say from personal experience, though I prefer AMD to Intel(Processors), I can vote for an older generation Intel SSD. Since you require a SATA II Disc, I'd say, going for an Intel X25-M 160GB older model will be worth it. It's a tad faster than the 80GB counterpart, small form factor (2.5) and should be a lot cheaper now then it was 2 years ago.
Newegg says only 120GB models available at 240$

My 80GB model cost me a little more than that 2 years ago.
