Hmm. Having seen some of the fit and inaccuracy issues with many Trumpeter kits, which are not cheap, I think I'd wait and see first. Fortunately, BB has one on the way, so that should help!
I think any fit problems with this aircraft type could seriously affect its construction, and the look of the finished model, due to the design, and especially the fact that it's a biplane.
Having said that, if any problems are minor, it should be a very impressive model when completed. And bl**dy big!
