I would like to go with the Airfix Spitfire 22.
I have had the kit for a while, so now seems a good idea (I am not sure why it has not been re-released by Airfix). Its a hopefully not difficult kit to make and I think that I made the above silver version about 6 plus years ago. I gave the finished model to someone at work and watched over the weeks as bits gradually got broken off and lost in his office!
I just realised that @PlaStix made this kit for the Spitfire GB last year so I will be trying to lift his ideas. I won't be going down the etch route having seen the work done by PaStix - I cannot get that good level of finished work (a tiny folded etch seat -!!). That said I think I have a spare instrument panel and maybe a resin seat and some Eduard spares along with a Xtradecals set.
