WordMan is too kind 
Enright3 asked how I got into modelling, why I like resin, and what else I’ve tried.
Ahem. Like every boy of my age group, I had fiddled a bit with models, but the real turning point was in 5th grade, when a couple friends brought some model cars to school that they had customized. Holy cow, you didn’t have to follow the instructions! You could mix and match parts between kits! It was a revelation; I went home and tore apart two model cars I’d built and rebuilt them.
So I built model cars for years, trying to put my own spin on every one, trying to build each one a bit better.
My second revelation was when I bought one of the old Monogram halftrack kits, and inside was a little pamphlet Monogram had commissioned from Shep Paine,explaining how to build a little scene (a diorama) to set your model in. It was my first view of a bigger, wider, more interesting world of modeling.
And then one day I stumbled over a garage kit site, where people sold resin kits of monsters and girls. And about simultaneously I went to my first SciFan, a local model contest specializing in fantasy and science fiction.
I decided I’d had about enough of wiring engines and routing brake lines in 1/25th scale, and ever since I’ve build fantasy and sci-fi. The pulp novels of the 30s and 40s appeal to me with the vivid cover art, so what I usually build is pulp-inpired. That, and the occasional girl kit.
With girl and monster kits, the emphasis is on the painting; the kits typically have very few parts. So I got a set of oils and taught myself to paint figures, using Shep Paine’s How to Build Dioramas as my Bible.
And I also started building spaceships and suchlike out of my own head. Usually I start with a kit to get a basic shape, and then add or subtract, hack and glue, until I get something I like. Super detailing doesn’t especially appeal to me, and research about what color scheme Tiger tanks wore during late 1944 certainly doesn’t; so I build fantasy subjects where I can concentrate on what I like: Trying to build something with the “Wow!” factor.
So if you want to get started, I’d buy a nice modern kit of whatever subject appeals to you. Building a model, properly, takes a significant amount of time and money, so make sure you really like the subject. A beginner doesn’t need fancy tools or an airbrush; what he needs is practice in the basics: Getting parts to fit properly, making seams disappear, not getting glue on the windscreen
, surface preparation, and laying down a smooth even paint job.
Find a local model club and attend meetings. Even if they build tanks and you build dragsters, there’s something to be learned by talking to other modelers.
And don’t be afraid to put your own spin on things. Maybe you think a car rides too high in front, or would look better with a big blower on the engine; maybe you don’t like the gas drums that mount to the rear hull o fa T-34. Make your own gas drums; swap on a blower from another kit. And try to think about the big picture, the artistic result you’re trying to achieve.
Why do I like resin? If you have an interest in pinup girls or horror movie characters, resin is your friend. There are lots of resin figure kits out there, of subjects you’d never imagine would be kitted. They’re expensive, but they’re available. And resin figures are easy to repose (cut apart, pin the bits together with brass rod, bent to the pose you like; fill in the gaps with epoxy putty). Buc Wheat’s website has a useful roundup of the year’s resin kits: http://www.bucwheat.com/2k17/2k17.htm
But spaceships and other mechanical devices I usually use styrene for; it’s better suited to flat surfaces and complicated mechanisms.
Bla blah blah, that guy talks a lot. Time to shut up now. 
PS: Oh, here’s a link to my Photobucket albums: Photo Storage
PPS: One-sentence advice for various genres:
Cars: Bare-Metal Foil is your friend!
Armor: Learn to do washes and drybrushing
Airplanes: I got nothin’
Star Trek: Aztec Dummy pre-cut painting masks
Figures: Exaggerate shadows and highlights
Okay, I’m really shutting up now.
