Hi Skbass,
I am also new to the Neo Scene, I just traded a PS2 for a converted Neo Geo Cabinet. Mine came with a 2 Slot board. This one is good because it has the memory card!
The guy I got mine from has 2 extra 1 slot boards. I think he has them for sale on his website for $75.00. He is a good guy to deal with, I am buying another cabinet from him tommorow (Atari Xevious).
Check out his homepage @ <a href="http://www.geocities.com/ksink98072." target="_blank">www.geocities.com/ksink98072.</a>
His name is Keith, you can send him an email or probably call him. He has a nice collection of MVS games for sale too, very reasonable.
I just picked up another game from him today "Shock Troopers". He is very friendly and helpful.
You can also buy a 4 slot Board from MD Game Sales on Ebay... they sell alot of MVS games, their 4 slot boards go for $175.00 with buy it now.
Have Fun,
Robert
