Hello,

I use ExpressPCB and have had no problem either modifying an existing device or creating my own devices. Aside from the fact that the pcb drawing program doesn't create the "Normal" types of files like gerber so I can take my drawings and go to any pcb house, I like the program alot and have been using it for over 5 years. ExpressPCB has done many 2 and 4 layer boards for me and they do a nice job.
