I really like my 6x8 Harbor Freight one. They didn't have the 10x12 when I bought it. We don't get snow here, so I'm not sure how it hold up to that, but wind and rain are no problem. I've only had a little problem with the roof panels slipping at first, but they are ok now. Here's a recent pic. It's heated by a 1500 watt space heater and I've lined it with bubble wrap. It stayed at 55 even when the temps were under 20. My husband built the foundation and put it together.
