I have a tc33d with a curtis cab, heater, wiper, soft sides and work lights. Overall it is not a bad setup. It has only fogged once in two years and that was a really wet day. I blow snow on 120 driveways so it gets a work out. With the heater I can work in a light sweater on cold days. (I live in Ottawa, Canada) It is not anywhere near air tight and when driving from spot to spot it can get really cold when the wind blows in the holes. If I remember correctly I had a choice of a soft cab for $2000, this curtis cab for about $4000 and a laurin cab for $7000. THe laurin is a much better cab but quite a few more dollars. There are some pics of my cab on this site. Try searching under "dylan"
