The one you referenced is an 80 gig version which may not live up to the 120 gig but certainly give great performance..
Myself, for the price, I would opt for a 120/128 gig SSD (either the Vortex 2 or the C300) With the C3 you would need the U3S6 card unless you have the U3 and Sata6 on board. That card would give you U3 and SATA 6 support (If you do not have) which getting the Reco you would not get.
Added, the vortex 2 will not gain from being on the U3S6 card (I put my Intel G2 on it and it shows up as a Sata II drive, which it should)
I would think that other people would want to use the RevoDrive if they new the details about it.
From the link you gave and thanks for that link, it looks like trim will not work with the RevoDrive.
Maybe I should wait for trim to work on a raid architecture as the RevoDrive uses RAID.
I really dont want to buy any SSD unless it is a SATA III.
So right now it looks like the Crucial C300 128 plus the AUSUS U3S6 card it the best way to go for now.
I wont be getting anything until November (I do all my builds in the winter) so I will see what technology changes there are and see if more SATA III will be comming out or RAID trim will be supported.
