Mine is to continue liquidating my 1/32 WWII stash and turn to 1/32 WWI modelling exclusively.
I've sold some very nice 1/32 kits - Tamiya Spitfire, Mustang & Corsair, HK B-25J (until I bought the Felixstowe, my most expensive purchase ever), MDC's Ar234, Jerry Rutman's Mustang, numerous Hasegawa 109G's, Trumpeters superb Avenger kit, all three Pacific Coast Macchi's, Trumpeters P47 Razorback and Hasegawa's Bubbletop version.
I don't regret it at all. I have used the funds to bolster my WWI 1/32 kit stash, and I'd never have been able to build so many anway.
Once I built my first 1/32 WWI kit - Encore's SE.5a - I was hooked. I think it's because of the variety of skills needed, the relatively small amount of space a completed model takes up, the scope for great paint jobs, the fact that you've to represent canvas, wood & metal next to each other. The rigging grows on you & really gives a model the finished look. The character WWI planes have is pretty unique. I just found a Spitfire or Mustang a bit boring in comparison.
Perhaps most importantly, WWI modelling doesn't seem to have rivet counters - people who just criticise a build for some perceived inaccuracy - they have no other purpose than to spot "mistakes". Perhaps it's the lack of reference material, especially colour photo's, but I've not experienced anything like that, especially here.
So, I'm making good progress already - added a few kits, just need to sell a few - anybody want some 1/32 WWII kits?!
