It's a tangential point, but I'l make it anyway. Be very careful with the fab houses which offer you "free" design software -- there's usually a catch of some sort. ExpressPCB is particularly bad. Their software exports to a format which is only readable by their factory. Therefore, once you do a design with their software, then you're locked into using their fab services forever. To belabor the obvious: ExpressPCB's software will not generate Gerbers. Yes, some people will say "Oh I don't care! I'm only doing a one-off board." However, the fact is that one almost never does a one-off. You'll find some errors in your design, and you'll need to respin. Or you'll want to incorporate large parts of your board into a larger design after you have proved it out. Or you make a prototype, and then your sales department will sell ten of your designs before you can say "respin!". And what do you do if ExpressPCB ever goes out of business? Your designs will be lost forever. Or what if they decide to "monetize their web presence" by jacking up their fees? You'll have no choice but to pay. Although the gEDA/PCB design flow might not seem as spiffy and easy to use as that offered by ExpressPCB's stuff [1], gEDA/PCB does output fully standard Gerber files which you can take anywhere. It's all about who controls your design, and using gEDA, it's *you* who controls it. Cheers, Stuart [1] Soon to change, due to our collaboration with the Linux Fund!
