Late to the show on this, but enjoyed the posts.
I picked up one of these on sale, grabbed the interface board and the haptics upgrade kit. I gotta say, the footprint is pretty good, I was about to make a full sized pinball table, but the spot I had for it wouldn't take it, and an internet journey landed me at the legends pinball and as luck would have it, they had one sitting in a box in a local store (in a tiny town).
I used to build virtual pinball into my cabinets, and the one big cab I kept still has the flipper buttons, but it wasn't the same as the vertical table. I thought this was a good way to jump back into it. (plus as an added bonus PBJ doesn't like them, in fact, they come up a couple of notches for that, sorry Jim)
The only thing I plan is to upgrade the backglass and install a permanent micro pc. I haven't even tried the PC interface yet (renovating the basement around it), so tons of potential. It's perfect for a ski chalet up in the mountains, as it sits over the wet boots.
Overall, it's not a bad option for a starting point, hell add in the price of wood/materials lately and it's maybe even an economically sound base.
