Easy question. Don't like them, unless the game was originally designed for 'em. Don't have any of those in any of my games. (Trick statement, since I ONLY own TZ at this point.)
However, I understand what you're trying to point out, and yes, again, that's why I said it is personal preference only. Color DMD and a shaker motor doesn't fix anything broken, or make anything technology or maintenance-free on the game, it's all for the player's preference.
I LIKE the original sounds, it's what 'I grew up with', and to me, the game doesn't need any remixes or new sounds, etc.
When I have a really bad first or second ball, I'll restart my game as I'm plunging the ball. Rod will start to say 'You have just crossed over into..' and then get cut off by the slot machine noise. Apparently, the pinsound board has more voices, and so doesn't cut him off. No thanks. My current audio board works fine so I don't need to replace a bad / missing board.. and if it doesn't perform *exactly* like the original (added features are fine..!) plus the cost, this is out of my interest range.
(As a side note - referencing cost.. think we could have saved about $15 and NOT had 'light up' trimmer resistors? Was the back-lit controls really necessary, or just some bling? )
