Don't forget mentioning there are other options.
We use SQL Zip, as SQL Lite speed had issues with Named Instances. I belive this has been corrected, but dealing with the tecnical support staff was extremely painful.
Based on our tests SQL Zip ( www.sqlzip.com ), performed just as well, and only cost 500.00 per server.
Also support from SQL Lite speed was difficult, and there were issues with the documentation not matching the product features.
SQL Lite Speed has lots of advertising flash and industry support from magazines and such, but didn't deliver the goods based on the price.
