Original board adds more value IMHO, so whatever you decide keep the original board with the machine in case you decide to sell later.
Same for original DMD vs LED or Color LED. It's personal preference, but being old school I reckon original plasma DMD is the way to go. The sharp LED pixels don't look as good to me.

When I researched, this is what I came up with...

Pinled - works fine with original light bulbs, LED lamps can ghost
Rottendog - some people report problem boards, others say it's fine so go by what the masses say.
XPin - works fine with LED and original bulbs. If you experience flicker on the DMD, change the scan rate form 2x to 1x to suit original Plasma DMD.
Nb. Brett at XPin told me he has a new board in the works, hence why they are currently in short supply.

If it's a HV problem, avoid piggy back plug and play boards. The word is most (probably the no-name boards) are not rated for the correct voltage and can burn out.
