Well I purchased Residential Wire Pro v2 from CMH Software. So far I have to say it is really helpful and has the "gadgets and gizmos" that are necessary to put a plan together. NO more erasing colored pencils marks - Easy to learn and make changes as needed. Single user license cost me $99.00 so worth the investment.

Also, hooked computer up to 44" TV so now I can do the plans on a large life-like layout; much easier than having to zoom in-out etc on a large layout.

Don't know if a large electrical contractor will like it but for me, mainly a residential electrician (owner operated) it fits my needs.
