I was one of the first group of people to order from Big Sky, and after a delivery delay of 2 years and 3 months I can state that for me there won't be any recent experiences.
Also, it was more than a delivery delay that people were dealing with. Big Sky consistently misled people as to delivery status. They (he) would return emails about tent information, but not about refunds or delivery. Bottom line is that I simply wouldn't trust the company under any circumstances.
Good luck if you decide to go with them, though, and report back what your experience was.
