im using 2 SSD's in my rig. 1x128GB OCZ Vertex and the other is 256GB Samsung. To be honest they are worth the price you pay for them. Atleast i saw massive load time decrease in all the applications that i had installed and ran through the ssd.
Btw i think 15k for a 60GB SSD isnt too expensive....considering you can put your OS and a couple of games on it as well.
