Hi Mr Deb and Aardvark,
I might try for the free 500, although I've only run out of holes once. The bit I didn't find intuitive was libraries.
I ususally know what I'm trying to make so I don't bother with a schematic, I just go straight to PCB layout. I usually make my own patterns, it's often quicker than trying to find them (if they exist) in the supplied or downloaded libraries. I either make them directly in the PCB layout, then copy to a library or use Pattern Editor.
Aardvark, when you say you can't force a s/s board, are you refering to the PCB layout? The default is always d/s but unless you select the other side it will remain on one side i.e. s/s.
The exception is SMD components which by default go on the copper side as they should.
Vias are useful for linking up to the other side of a d/s board. If you use through holes with d/s, when you print out the other side, you can leave out the pins (e.g. a MicroP) on the side that the IC is mounted. Same apples to any top mounted through hole components. The vias remain on both sides.
I make my own boards using toner transfer, I can't get them as small as professional ones but fine for me
1mm is about the smallest trace I attempt.
I don't do much smd stuff, voltage regs, 1206 caps and resistors, anything smaller I can't see let alone solder!
