Should I use JQueryUI in my project?

I've been playing around with JQueryUI for my latest project. I've run into some issues and questions, and I've not been able to solve them either myself or with the help of SO.

Here's my current impression:

• Styling the UI seems quite daunting .. a lot of "framework" to understand before being able to do stuff
• not much help either by googling or by asking questions on SO .. doesn't look like there is a huge community to support it

What is your opinion? Should I "tough it out" (I admit that this may be more my problem than a problem of JQueryUI) or should I look for alternatives?

I would perservere with it, but bear in mind that if you have what seems to be an insurmountable problem with a particular control there's generally an alternate version available in one of the many blog posts that have sprung up about JQuery.

By sticking with the framework, you'll learn how to extend it yourself, which will allow you to introduce new functionality (for instance, I recently wrote an internationalisation component in JQuery that allows me to retrieve resource strings from a web method via AJAX calls in ASP.NET).
