My Mom bought this one at an Ulta store in California last time we were on vacation:

She just picked it out herself without any help from sales associates or what have you. That said, she'd previously had a "Hot Tools" brand flat iron that she liked, but ended up leaving it in a hotel room by accident on a previous vacation. At least she knew she liked the brand.
Anyway - I tried this one myself a few times during our CA vacation - quite liked it. Not nearly as expensive as some of the higher-end brands, but this thing works like a dream! I have fine, straight hair - though lots of it. Battle lots of frizziness and so on. This particular flat iron that my Mom bought is way better than the 'Chi' one I have. I'm tempted to get one myself. It works beautifully and quite quickly. Doesn't seem like you need multiple passes through the hair to get it straightened. It's fast and works well, imo.
Note: I tried to find this on Ulta's website, but didn't find it online. We bought it at Ulta in the store.
I like this flat-iron and would like to get one myself, after trying the one my Mom bought.
eta: found it on Ulta's site after all:
