I hear you Rob, I also have a wnw se5 waiting to be built but it looks so good in the box I keep convincing myself I am not yet good enough to build it !
As for the "long term builds" I am busy with the 1/32 Tam P-51, I see all these nice builds of them on the forum and expect myne to just fal together in a week like the other Tam kits but allas.
Every time I think I make progress there is something else to add before the cockpit area is completed. It is not a difficult kit....there is just so much of it.
I have found thet when I cet into a slump building-wize I hall out a simple quick build and finnish that just to get the sence of "I completed a model" back.
Good luck with the build
