My favorite are Bright Bots. They are from Australia, I think, but you can find them online. I bought them from www.theecstore.com They are pricey, but the ones I bought for my son are still in like new condition for my daughter so I guess it depends on if you would reuse them or not. Bright bots have some kind of microfiber layer inside a terry cloth outside so they hold a lot of wetness. And they come in cute colors.
For me, the Gerber ones didn't hold wetness -- they just were not much better than regular underwear. I did like the JC Penney brand ones, but can't remember the name. Maybe it was Wee Ones?
