which trackball best for centipede machine?

[rchadd]

i see these two trackballs for sale in US on ebay

the "buy now" price for the 2nd one is $20 more

which one would be the best to get?

it think the bottom one is a happ model (as looks same as my GT 3" TB)

The second one is based on the Atari design, which was used in Centipede. Neither one is "correct", to be correct you need the smaller version of the second design pictured.

i assume either would play the same as if an original centipede trackball?

is it worth trying to find an original centipede trackball instead?

any ideas where to get one?

my posting on BYOAC buy/sell forum has not resulted in anything.

bob roberts seems to only sell parts (and not accept paypal which means difficult for overseas purchase)

If you found an original, you'd end up having to replace the bearings, probably the rollers too, and then if you were unhappy with the old ball, a new ball. Basically, you will have replaced everything but the optics, wires and plastic housing. Total money spent would be close to that of a new one... (depending on brand)

Just keep in mind you need 2 1/4".

What's the new millipede/centipede machine using?  I'd just pick up the 2 1/4" Happs.  Believe it was 2 1/4", definitely not  3" like the ones above.  Like Paige said, I think Happs is using the Atari design so should be pretty similar if not identical.

the above are photos of 2 1/4" ones

i'm going for the imperial...

i emailed seller direct and is willing to ship to UK

I have a 3 inch Imperial like the first one pictured. Centepede plays great with it in MAME.
