most model kits are made from thin pieces of styrene, the model glue used partially dissolves the plastic and forms the bond between pieces, resin kits are solid pieces of material that need epoxy or superglue to join together, essentially they're small statues.

ebay is usually the cheapest spot to find kits but I often look on hobbyfan.com, e2046.com, and hlj.com, there are hundreds of kits, and the pictures are quite helpfull. It's more expensive at hobbylink japan (hlj.com) but they sell original castings, the artists get paid for thier work, and you get nice box art and usually a better quality kit
And if you've never seen any of these kits, there are two I've done in my fanart gallery!
