The instructions are lousy and the kit was way overpriced when it was first released. I bought it about 5 years after for a much more realistic price but have yet to build it.
I may actually end up putting it on ebay if the Trumpy version looks to be an easier build.
I would await the Trumpeter version - if nothing else, the instructions will be way batter.
The Trumpeter 1/35 Bismarck is around £100GBP here in the UK. Having had the Tamiya, then the Revell version, I won't be bothering with the Bismarck from Trumpeter. I will however be looking closely at the Scharnhorst in 1/350 if it ever materializes in future.
