Quoted from f3honda4me:If you have 5.0/7.5 boards and you haven't had an issue, that really should come with a "yet" at the end. If you've had the game for 3 or 5 years it doesn't really matter. It doesn't seem to be a time factor but a games played factor. I don't think we've seen any WOZ games with a few thousand plays on them with 5.0/7.5 boards that didn't have a board go out? I've searched for such an example, but haven't found one, so if anyone has one please share!
In my searching there were a fair number of used HUO buyers that have been burned on the old boards, buying from users who had their pin for years and never had problems, only to play a bunch of games and then have boards go out. It's just too much of a risk for me, unless the prices become more reasonable for that risk. 2.0 boards are the only ones that are truly 100% to last as long as any normal LED board should. I'm in the market for a WOZ myself right now, but the prices on HUO are too high given that 2.0 boards are $800 and about 12 hours of work to install them.
Personally, I wouldn't touch any model WOZ without the new lighting system as I had to change out my ECLE's whole 7.5 lamp board set not once, but most of the boards twice and some of the boards failed a third time. I know a person that had their game in the same shipment as mine and has not encountered one lamp problem. Build date was Fall 2013. Two of the four ECLE's in that same shipment had lamp board issues, the other two nothing. I know some guys with RR WOZ games that currently have lamp problems, so in my mind the best thing is buying a WOZ with the 2.0 lamp kit installed, anything else is a crap shoot.
