Angular Bootstrap's Typeahead directive does this job pretty well, although we've had to do some template overriding and funky directives to get the functionality we needed (e.g. switching the results to a different set by clicking an item in the dropdown). Glad to see more alternatives being made out there. Nice job!

I too am a fan of the UI Bootstrap typeahead - it's simple, and works nicely. It's not as robust as select2 or whatnot though as you've pointed out.
