Does anyone know of a good php polls. I need one that allows comments. I only found one on hotscripts.com that allows comments and I didn't like that one.

It's probably the one you have already tried (I found it on Hotscripts about a year ago), but I found this system very good:
Advanced Poll (http://proxy2.de/scripts.php)

I've used something called phpQ for some fairly sophisticated surveys, but it's not free. I think we paid $150 for v.1 of phpQ last year. You can see it here: http://www.chumpsoft.com/

Easy to build the polls, choice of how to display results, etc. I think there's even a download feature in a couple of different formats (including MS Excel). Nice product -- we're about to upgrade to v2.1.

It depends what kind of system you need. You might go with a free one or a paid one or get a custom made solution !!

Cost and Requirements matter !!
