It's a slippery slope, Eagle90. I've always loved dinosaurs and prehistoric animals. But the models that are generally available are either resin kits or out-of-print vinyl kits that are way too expensive for the general modeling public.
For a brief moment it was thought that Pegasus Hobbies would step into the breach with their affordable 1/24th scale vinyl kits. But this line is now extinct thanks to either poor marketing or poor sales. Only three models were produced. Two of them have two animals in them so you could say that five dinosaur models were released. There is Triceratops, a Tyrannosaurus rex and a juvenile Triceratops, and Spinosaurus with a dwarf Xiphactinus audax. I have all of them in primer waiting for me to get the nerve to paint them.
But the thought of prehistoric models in 1/24th scale with all of those other modern figures and models in that scale was too much to resist --- I was hooked! It's one thing to have a great model of a dinosaur on your shelf. But if you have a model of the family car and a figure in the same scale it really brings home how large these animals were. So that's what I'm doing now, collecting dinosaur models in 24th scale (or thereabouts) or sculpting my own because a particular animal is not available.
So be careful. Dinosaurs may bite you back.
