Fabrik is a wonderful extension.
I used Fabrik to make database apps for several non-profit organizations who needed to store and track information about the clients that were passing through their programs. These organizations were using paper forms that had been around for years, and some were manually entering everything into these horrifying, bloated excel spreadsheets. "Unsophisticated" would be an understatement. It was my job to take their paper forms and excel monstrosities and figure out how to translate it all into an app for entering, viewing and managing client data.
I am by no means a professional, but with Fabrik I was able to design and maintain a stable, aesthetically pleasing and idiot-proof database app. Without the flexibility and sophistication of Fabrik this project would have been a nightmare.
Regarding support, I am a bronze subscriber and my experience with the Fabrik team has been uniformly positive. I recently ran across a bug (a simple 'oops' that they had apparenly overlooked). I made a post to the forum with the error message. Two hours later a new SVN rev was out, bug fixed. Thanks Hugh!
Frankly, I think I've been spoiled by the level of support. If a reply to a question doesn't happen within 24 hours I start to wonder if there has been some terrible accident. I'm only half-joking: support through the Fabrik forum has been very consistent and very good, and this has been the case for the past two years of using Fabrik for work and personal projects.
One minor critical note: Fabrik lets you do a wide variety of sophisticated stuff. With this flexibility comes a moderately steep learning curve. However, I think it's well worth your time to learn the ins-and-outs of this extension.
