We just switched to Target's "up" brand, and so far they are pretty good and much cheaper than pampers. But, we only use them at night and my son only uses/wets them every other day or so. So for light use, they are excellent.
As much as I love Target's up & up brand of diapers, I was really disappointed in their training pants (sizes run SMALL & leaks). I did, however, have good luck with Walgreens generic brand of training pants. They have great sales (BOGO free or BOGO 1/2 price).
Re: Other than Pampers Easy Ups and Huggies Pull Ups...
if you are really PT'ing - just use underwear.... pullups are just like diapers and do not give a wet sensation that kids need to really PT well.
Definitely this!! We use the Target brand, which isn't as expensive as the others. DS only wears one at night, and they have been great.
