Yeah you mentionned that you would soon be switching over. Welcome to 1:200 collecting!
The plastic models (Skymarks, Hogan...) don't look that bad. Actually they look pretty good. Obviously not as much detail as diecast, but good nonetheless.
You should buy one just to see if you like it. Nothing to lose really...
So far in 1:200 I have
- Gemini: Amercian Airlines 737-800
- Gemini: Air Canada A321
- Hogan: Airbus A380 (house livery)
- Inflight: Air Canada 747-100
The Inflight is absolutely awesome! You'll love your British Airways 747........I mean 747s..... Wait aren't you supposed to be cutting your spending
