I love the wood joystick base as it is Keranu, don't change a thing!
Be careful shopping for pcb's, it quickly becomes more addictive than collecting 'regular' video games.
I can totally see me becomming addicted to collecting the crappiest arcade PCBs out there.
You should be able to easily find POW for under $10. Thats what I'd recommend anyone to start with when buying jamma pcbs.
Its not that easy nabbing a arcade pcb of POW. It usually goes for 20-40 bucks on ebay but isnt super common,local vendors here charge more,because its a sure bet to make them money on a location. However,everynow and then,you can locate a vendor who will sell you the whole arcade cab complete of the game for around 100-150 bucks.
Also,that pcb was really long,kinda flimsy without all the feet in place,and because of being flimsy could get damaged easy. Awesome game however,def worth picking up if you can get a fully working board.
