My recommendation, based on reading trade journals, seeing
demos, etc. is to go with the SGI. They tend to have much better
price/performance than E&S, and SGI is widely considered to be the
best managed company in the U.S. (maybe not saying much ;-)), so it's
not like you would be taking a risk or anything.
