There's a thing that bugs me about Strataframe demo. It only lasts for 20 days. It's not that long to really evaluate it. The thing is that I don't have 20 days to just do that. Are they flexible about that number of days of evaluation? I mean can I get more days if I ask?

I also recommend Strataframe. And, IMHO, 20 days is more than enough time to be convinced that you want to use it. I have cranked out over 80% of a new C# application that I am building using Strataframe in about that long.
