In the past, I used New Wave Concept's
Livewire for design/simulation and the same company's
PCB Wizard for pcb layout. Both seem to be geared more to students and hobbyists and are relatively cheap compared to other packages that I have seen available.
I currently use Abacom's from the same company to design stripboard or breadboard layouts. I prefer breadboarding to running simulations. All of Abacom's programs are very reasonably priced.
Two free programs that I have used and are nice would be
TinyCad for schematic design and
**broken link removed** for schematic design and pcb layout.
I also own
**broken link removed**, but rarely use it anymore. I can accomplish the same things (minus simulation) much faster using the programs from Abacom.
I have recently been trying out the free version of Novarm's
DipTrace and it seems pretty nice. It is pretty easy to use compared to a number of other "professional quality" schematic capture/pcb design suites that I have used in the past. It
feels similar to using the Abacom programs. From the site, these are its limitations - "Freeware edition does not support export to DXF, Gerber and N/C Drill, maximum number of pins — 250." It has not earned my commitment just yet...
