[time-nuts] Schematic capture, anyone?

I'll add my $0.01 (depreciated).
I am working on a project with Eagle. I started with the Gnu cad
stuff but like many free software projects, it has multiple user
interfaces and clunks. I tired of it and switched to Eagle.
Eagle also has quirks but has the ability to switch back and forth
between schematic and layout. I have added parts with the XML format
and while painful, it's not impossible. Also, the user library of
scripts is very useful: there is one that converts the schematic to a
SPICE netlist (suitable for LTSpice with a little massaging).
If/when I need a larger board than the free version then I'll have to
decide what to do. But for the time being, it's OK.
(And, as I like to say, when it comes to advice, you get what you pay for).
