I generally build up on Velleman ecs1/2. That's what is pictured. $4 if you you shop around, or find other similar brands for less (with more dubious quality hole spacing (uneven) and pad quality - I've never had a pad lift with multiple soldering/unsolderings for example.) Futurlec sells inexpenive cards, I haven't trued theirs.
The ecs1/2 is 80x100mm, I like using that because that's what eagle will support, and expresspcb also I believe.
I have also used ecs1/h when I needed something quick and just cut it in half or into the size pieces I needed.
The picture below shows 6 pieces of ecs1/2, with cut-down ecs1/h filling the gap in the middle left & right.
Parts of the 2 small cards were incorporated with the standalone arduino to make the card above, which does not do the time & score lights, but just the score detect & Lights & sound creation, & drives a remote set of lights.
The wires wrap around the pine about 5 turns around a square post if you do it right, and they do not come off or get loose. You hold the wire as you start twirling the wrapper, and the wire goes on nice & tight. You have to physically unwrap it to get it off, it won't slide off if its not really loosened up first.
I wish I had a wrapped up board at home to take a better, closer picture.
I do mine manually, you can buy an expensive squeeze handle wrapper also, just gets in the way as far as I'm concerned tho.
