I think you'll get more value from local Meetups and the very few non-marketing conferences out there. If it's a tech company putting on a conference, expect a lot of marketing. Conferences like Strangeloop and the no-fluff ones are usually better.

Other than that, books and screencasts seem to be a good way to spend that training budget as well. But there's a ton of videos online available for free too.

Of course, they all require time. Which is money. :)
