Well, I got a few intel ssd drives, had them installed on my workhorse at home and they run like hell on earth.
If you are using windows, you need 7 to support ssd trimming, otherwise with other os (except linux of course) in a few months you will have a sloooooooow ssd, I have one on my laptop, where i'm writing this how, and the solutions is ghosting every 4 months more or less, this method wipes the ssd solving the trimming stuff from xp.
You won't get many space with that budget, my INTEL SSDSA2M080 are 80Gb and its price tag goes around 120€, they read around the 300MB/s and write around 200MB/s.
On my laptop I have an OCZ Vertex 2 with 120GB and its price went on last summer around the 250€.
You have other brands, its a matter of finding one inside your budget and google around its perfomance, controller chip and its reviews.
If you find something, post here and I'll have a look at it.
