Hmm, I have been reading these threads with interest and I have hesitated to venture into the conversation, but why not.
There is a freeware B-17 in ETO that is accessible to everyone and no one has to pay for it. May not be the model you want but it may be useful. Second there are 4 Lancasters in ETO that are free to all (these are not the Lancasters at AvH/GC).
Of course you must take my musings with a grain of salt since I do have a very biased view point. I don't like to pay for things that are available for free.
