Let me echo ...hello.....hello....hello...
I have had very complex board built with these tools. If the boards
anyone else is trying to build dont work it is probably do to the
manufacturing process of the boards and not due to the design tools. Hey
if you can attach a bga with a toaster more power to you (or the oven
got the bread the right collor of brown). using companies that are good
at depositing 900 pin bgas has been successfull.

I have recieved 2 prototypes of my design DSPCARD from ProtoExpress.
It was designed using gEDA and PCB. It is 4 layer 6mil
track/space. I have posted some information about it and pictures
of the bare board at http://dlharmon.com/dspcard/index.html Sorry
about the bad scans. The BGA part is a FPGA (256 balls, 1mm pitch)
I plan to try soldering it in a toaster oven. The board is about the
size of a credit card. Thanks to the developers for making this
design possible.
I'm very curious to know your results from the toaster oven when you
try it. I just received a tabletop reflow oven (a purpose-built one
;)) and will be attempting a BGA (Xilinx CPLD) in it soon. Good luck
with your efforts.
And I echo your "thanks" to the PCB developers...I sent out two
layouts yesterday, and I will likely be sending out a third today if I
can un-wrangle a few traces, all done with PCB (GTK version) on a Sun
UltraSPARC workstation running Solaris9.
