Yes those are the current two options.
We have spoke to some other vendors but they were pretty out of the ball park as far as pricing goes. The 3PAR seems to have a lot more features than PURE does currently (they are pretty new) but they both seem to be able to provide the performance and reliability. We actually just made the decision to go with the 3PAR today because we found out compression should be out by the end of the year (November to be exact) and they are going to guarantee the usable space to match the PURE.
I haven't seen the EULA. Is it on their website?
