What is the best home staging/redesign furniture planner?

My home staging and redesign business is going strong but am considering adding a visual aid not just for myself but for the client. I know there are many such programs online which would require I take my computer with me when I visit clients and/or my clients have a computer to view the CD I create for them. Which online source or program is recommended for my purpose? I am primarily interested however in the planners which are not on the computer but utilize repositional pieces on a flat 1/4 clear grid. They come with assorted furniture, accessories, walls, windows, doors, etc...pieces which are used to basically create a blue print of sorts, complete with furniture placement. I know there are several available, some inexpensive and some quite expensive, including a professional option which is very pricey. Does anyone have experience with these and if so which would you recommend for the purpose of staging and redesign? I would like to be able to play around with the pieces, which would assist me in coming up with a final design before I enter the home for staging, and I would appreciate the ability to photocopy the design for my records.
