What's the maximum you would go for resin terrain around the size as Sector Imperials ruins with the two statues. Let's assume for this hypothetical situation it's something that you really want to buy and it's within your budget to do so. How high would you be willing to go? Or what do you think a fair price would be?
Would and have paid $200 or so, maybe up to $300 if it's a
really good piece. Though I'm going to be very picky about it, most terrain I've seen does not meet that standard. Look up the old
FW city ruins as an example of the minimum quality required to get that price. They're nicely detailed and very solid blocks of resin.
Likewise what's the maximum price you would pay for a hero type character such as a terminator in resin.
Around the $50-75 range, maybe up to $100 for something amazing that perfectly fits the image I have for that unit. And again, you'd better be doing something to earn that price.
