Need wide angle camera and have 150 to Spend for photographing rooms and houses, would love a DSLR but think maybe out of budget, can anyone give me suggestions please. I understand the CCD sensor plays an important roll in this but getting so confused while looking, have found so far the only thing i can come up with is the Fuji FinePix S3200 which offers 24mm, i know you can add a fisheye but they are never very good and i dont want to spen to much.

Any help appreciated. Happy for second hand.
