you can get them for around $120, you might also look at the 100GB which can be had for around $150 or the 120GB version which is around $175. So for $100 more for the 2 drives you'd be getting like 60% more drive space if your going to stripe the drive together.
I upgraded from a 100GB w/2mb cache to the 120GB w/8mb cache and it was worth the extra $$'s spent, I could see the diff when loading and working on my photoshop files.
