I'm looking into sketching software today. Areasketch. Rapidsketch. Apex Medina. WinSketch. Too many choices. They all seem to range around $200. All seem like decent sketching programs. I don't need any bells & whistles; just need to draw exterior & additions, lines for interior walls, and text for labeling rooms. I do like adding in little graphics when it's slow (stairways, doors, etc) but it's not a nessessity. Thoughts on sketch software? Ones to avoid? Ones which stand out? Do any cost signifigantly higher / lower than $200. Do some have an annual fee versus a one time cost?
