What potty brand do you use?

I just went to get a potty for my daughter and felt overwhelmed with all the choices. I laid a few out and let her pick and she seemed to sit on the Bjorn plastic one a lot (the one that is like a chair) so I bought that. We havent used it yet b/c when I brought it home I thought the plasic might be uncomfortable or maybe other moms had different preferences? can you let me know what potty chair you use?
Thanks

I have boy/girl twins and tried 2 different potty chairs before finding the Baby Bjorn. I love them. The other chairs had the potty under the chair and they ended up leaking or spilling when I tried to remove them to empty. The Bjorn just lifts right out. Also, I liked the built in splash guard for my son and it doesn't seem to bother my daughter at all. They seem comfortable for my kids.

We tried both the Bjorn and the one with the removable soft seat (can't remember the brand -- it's white with a red "bowl"). Our daughter would use either of them -- she especially didn't like the Bjorn because she said it was cold on her tushie! The only thing we can get her to use consistently is a Blues Clues soft ring that we got at Target, placed on the big toilet.
