Simms are overpriced and cold.
Here is what I use. Low cost and warm.

I do all my shopping on the Internet to avoid taxes and such. Amazon.com is a good place to start. Get your boots 1 size bigger than your shoe size so as to fit over your stocking foot.
The reason for stocking foot waders over boot foot is if your boot foot gets a cut it's a pain to fix but your booties can take damage without hurting your waders.
