I only use aftermarket boards as quick test boards.
I've heard of and experienced too many quirky things with many aftermarket boards, so I don't rely on too many of them.
Quoted from cfh:but i never understood why anyone would replace that original board as it's the easiest thing to fix in pinball!
The thing is, a lot of people don't know how to do even simple board work, and would rather spend a lot of money on an aftermarket board. After all, newer is always better, right? 
While it's all well and good that you can put a "new" board in, they don't usually have schematics or thorough documentation like the original boards do.
