What Are Main Differences In Cabinetry?

Here's what I would ask the vendor: What is the material of the interior box (inside of the cabinet) and what is the material of the doors?. Then ask about the hardware - hidden heavy duty hinges? Do the drawer extensions go all the way out so you can access the back? These are the most important functional issues of cabinetry. Then comes finishes and stains. Then some door styles can cause the price to jump - a "no-reveal" cabinet vs. a cabinet door with "reveals". The only thing really worth paying for is a quality hardwood interior box (versus a MDF board) and higher quality hidden hinges and drawer extensions. The rest is pure style and finish with some types of wood species really running up the price. You can edit your question with more information and maybe I can offer some additional help.
