One can buy right now a MISTerFPGA from aliexpress for around €150 and that can emulate both MVS and AES. On this side of the pond, a VGA to SCART cable is all that's required to connect it to a CRT TV.
If instead one want the real HW, a working MVS PCB can be found for less that €100. A JAMMA cabinet would be the perfect place to use it, but with a supergun a CRT TV can give the same results. Cheap superguns can be found or built for around €30, fancy models can cost between €200 to €300 tho.
The carts aren't cheap tho, specially if original. I've only a battered "Puzzle Bobble" cart, it's a really fun game in PvP, but probably not the more iconic NeoGeo title.
