4 player MAME encoder

[fluentd]

I am slowly piecing together parts to build a 4 player MAME machine using a dual core computer as the brain of it. My question for inputs are about encoders. I just found a two player encoder at http://www.arcadebits.com.au/wiring/50-encoder-mame-pc-ps3-etc.html but not sure if everyone is buying two of these to make a 4 player MAME possible or if there is a 4 player encoder built for this purpose.

you could get something like this for 4 player. The I-Pac 4

Just came back to see if that exact part was sufficient enough. Thanks for the link
