I've been researching the UT for framework discussions, and from that I've gathered some information about the available frameworks, their http, and some of their advantages/disadvantages. I've found SEVEN different frameworks for VFP, and I would like your feedback on them. Of course I don't expect any one person to know about all seven frameworks, but I would like your comments on the one(s) you used. Specifically, I would like to hear about the following:

(1) Flexibility: how well does the framework equip you to deal with exceptions? Can you integrate other third party tools easily (end-user query / reporting tools for example.)
(2) Ease of learning: How long does it take to learn using the framework (well enough to start writing your first app.)
(3) Support: How responsive and how good is it? How much does it cost?
(4) Weight: How lean is the framework? How easy is it to distribute an application written with the framework? Are there any restrictions or run-time royalties?
(5) Main reason you selected the specific framework you are using today, and the main reason why you did not select a framework that you reviewed.

Your input is very much appreciated. Of course I've seen advice in the past to go and download all the demos for the frameworks and evaluate them yourself, but I think to learn all seven frameworks would take much more time than I have.

Here is what I gathered so far. I listed, in no particular order, the seven framework with comments from previous UT threads.
