I'm in SW Pa about 55 miles from Pittsburgh. Has anyone tried the small sunrooms from Thermo twin or another company? Even the Home depot poly lean-to units? If so what are your opinions and cost info? I want a small one like the approx 12 x 12 a house i've seen has. I would ask but it's been there for years and the current info wouldn't be the same now. I could get a quote from them but I don't want the other family members to know I want this until I have all the money put together to do it.
