I have bought several handguns from them and I have never had a problem, the counter staff has always been helpful and super polite. I have brought my own bore lock also never been an issue.
i have a quadrafire castile and i love it i would say that having one with a thermostat is necessary, the only thing i don't like about mine is the hopper is a little small it has a 40lbs capacity but its a tight fit.

looks like a scam to me according to these guys they want you to pay PayPal friends and family and that offers you no protection from scams!!!!
