How much do you want to spend? High end is Exo Terra tanks and some DIY. Middle is DIY (Home Depot, Lowes, Menards). Low end is some DIY, some Exo Terra stuff, and plastic containers. 10-20 gallon aquarium tanks from Petco and Petsmart are always good. You can go as expensive or as cheap as you want.
Wal Mart, Costco, Target. If you are looking for the best variety (and the most choices of clear containers you can actually see into) then I'd check the online equivalents of those stores, and also Amazon and other places.
Also, Really Useful Boxes. And model car display cases.
The sky is virtually the limit when it comes to invertebrate housing (provided ventilation is sufficient).
