Does anyone have a recommendation for home room design software? So far Microspot Interiors looks ok but it is 120.00 and one review mentioned that it uses UK sized windows, doors etc. I'm in the US and would like US dimensioned components. Is there anything else out there I should look at? I'm working on designing an addition and would only like to do basic layout and be able to do a 3d walkthrough. I'm going to let the contractor sweat the details.

Thanks
