I like the Altama combat boots I ordered from the Boot Campaign on Veteran's Day a few years ago. (Part of the proceeds go to veterans' charities; originally, it was for the Lone Survivor Foundation, but I think they've added others.) Boot Campaign site: http://www.bootcampaign.com/
For cowboy boots, I've had pretty good luck with Justin boots, though their sizing can be...questionable. Normally, I just go to some place like Langston's in the Stockyards and try boots until I find a pair that fit well and are in my price range. If you really want a selection, go to Justin, TX; I did that once a few years ago when my niece was living in Texas and wanted some boots. They have more stores with more boots than you can shake a stick at...
I've heard good things about Lucchese, but I've never owned a pair.
