70,000 is in the ball park, I purchased a SS7 kit in 2012 with most options, 912iS and firewall forward, Very complete avionics with Advanced 5600 EFIS and garmin com and transponder. All was purchased through Kitfox factory. I ended up at 75,000 all tools/accessories included. Unfortunately I am in WA. state and had to add 7,000 in sales tax because Wa. requires aircraft registration and sales tax must be paid just as if it were an automobile.
