Take a look at
www.embird.net it works great and is inexpensive. The basic program is $164.00 and Iconizer is $20.00. You can download a free demo, you can not save your designs with the demo. Embird will allow you to re-size, change colors, change formats, merge designs, split, rotate and a whole bunch of stuff. It's sold in modules so if later you decide you want to digitize you could purchase Studio module. I have a 6 needle embroidery machine and a single needle embroidery machine and I have used Embird since 2004 with no problems. Also when updates or upgrades are available they are only $20.00 or free. The big thousand dollar software is several hundred dollars to upgrade. My SIL bought one that was over 3K and was shocked and mad when she found out how much the upgrades cost.
