If you've never built a resin kit before, I would by a "starter" kit to learn the differences between working in resin and styrene, and to learn the intracies of photoetch parts. My first model in more than 30 years was a 1/700 resin Victory ship, and yes, I learned a lot from building it, so the second one actually turned out the way I wanted it.
My third kit was a 1/700 plastic Perry class frigate, and although I bought the aftermarket photoetch, there were construction differences, primarily using plastic model cement as opposed to cyanoacrylate glue. The big thing that kept throwing me off was the weight - resin ships, no matter what the size, have a certain amount of "heft" to them, which makes them less likely to wander off and fly through space. I was constantly misjuding how much force I needed to apply to the much lighter plastic kit, resulting in a few trips "over the side" of the construction area until I got the hang of it.
Learning on a smaller, cheaper kit is the way to go - yes, it's an additional expense, but in the long run, it will save you a LOT of aggravation, time and expense. BTDT!
