Enclosures - IRIS tubs or Animal Plastics(displays and racks)
UTH - Ultratherm heat pads or THG heat tape
Bedding - Local free newspaper, Cypress mulch(not sure on brand) from garden center, Harlan Teklad Aspen, America's Choice Eco Flakes.
Bowls - dollar store pet bowls. (I'm thinking about changing to delicups + pvc couplings)
Hides - dollar store cereal bowls, salad bowls, and kitty litter pans.
Domes - don't use lights or bulbs
Thermostat - Herpstat (nothing better than a Herpstat)
I think for reptile stuff in general, most products carried by Reptile Basics and Animal Plastics are great.
I have Sterilite/Rubbermaid tubs, but I think IRIS tubs are better. They're a little bit more pricy, but they stick with their tub designs. Sterilite and Rubbermaid change their tub designs often so if you want a replacement for a rack, it's almost impossible to find a replacement in a few years unless you stock up.
