Im like, metal, resin, plastic, kits, sculpts, tooth picks, fluff from under the cooker, whatever! Chuck it all in dem pot! Pour in super glue, mix with a stick and chuck some paint on. For me its always been about conversions, kit bashing and modifying. If I like a bit, a gun or a head or whatever, Im not bothered if its plastic or metal, bring it on!
I like plastic, as its easy to convert and usually you get more army per £. I like metal because it is stronger and does undercuts.
I started on military kits, mainly airfix planes, but also some other military bits. Mum bought some metal gobbos when I was about 9, and I loved the fantasy element. I went through the 30 marines in a box, the skeleton horde and the 3 rhinos for a tenner back in the day. I also really loved epic stuff. I also inherited loads of metal models from mates who went out of the hobby, plus spent a fair amount of £2.50 pocket monies on blister packs, so ran the whole gamut.
