Neo Geo is pretty great, but the CD is definitely not the way to go. It's pretty easy to either buy an MVS cabinet for less than $300 or consolize an MVS board with 2 joysticks using real arcade parts for less than $150 if you have a little technical know how. I'd be happy to post a brief walkthrough. CD just has worse load times than you'd imagine (more than two minutes in some cases) and the drives are notoriously flaky. AES looks great, and the carts and packaging look great (I have 30 or so), but MVS carts are way cheaper in most cases, and the converters often cost as much as an MVS cab. I'd recommend anyone who wants to play real games on real hardware just build a jamma supergun to use as a consolized MVS, and you can buy othe pcbs if you want that way, or just buy a cabinet if you have room. AES is fun to have and all, but it is definitely expensive. I would only recommend buying one to a wealthy collector or someone who always dreamed of having one as a kid to scratch that itch.
