Hmm I have an idea for a suitable third option for the awesome people like yourself. Since I have your attention already I'll go ahead and put it out here to get your opinion. I was contemplating putting together a one-shot collection that would feature encounters on one map from each set. For a total of 4 one shots. It was going to be a surprise option announced near the end of the campaign but no reason we can't have it in the addon shop and as a third choice for the complete collection tier.
I also understand how tight the budget can get when you back alot of projects. I do so as well. Each set is, at minimum, 1000 individual terrain pieces plus atleast 10 maps in numerous formats and variations. If I had taken this to print each set would be about $40. As a way to get this to people and save everyone money on shipping and manufacturing I went with a self-printed model which allowed me to cut the cost in half I have since reduced it a further $5 based on your feedback and others.
