Hi Bill,
an impossible task

. Do you want a full resin kit or a conversion?
Would you like early war or mid to late?
Best advice Bill is to choose a picture you like the look of and build on that. The resin kits are more challenging, at least for me, but the conversion sets are equally good.
If cost isn't an issue then start with the Bren Carrier No 2 Mk 1, if you like it then follow it with the Scout Carrier Mk I, Universal Carrier Mk I (all 3 are full resin kits), Universal Carrier Mk 2 (3 versions Possible) MG Carrrier (could be early or late), Mortar Carrrier, AOP Carrrier, Deep Wading Carrier(all conversions) and then finish on the T16 (full resin kit)
By the time you get through those the Windsor should have been released.
The first two have the open end engine so might be the most interesting.
I know you been contemplating one for a while now, just go for what you fancy.
