So just got this baby as a gift for sister's family.....but it's much less headache then my own retro arcade, might have a smaller games list, but it has all the games I'd actually play pretty much. But the best part is it's pretty much idiot proof, no setup just plug and play and teh abaility to one button switch on vertical is amazing for classic arcade games. You can finally play Pac-Man, SHMUP's, donkey kong, time pilot, galaga, etc etc in proper vertical orientation with one button and a rotating monitor. In any case I highly recommend..... it says sold out but they come in multiple flavors and like all amazon arcade units preloaded they just keep getting new entries. Look Up Pandora 3D Saga DX. It runs fantastic, and I love that this version has a trackball and I can play centipede vertical in proper ball fashion.
Also sound on board is good (no need for monitor with sound), and the led button light up room like an arcade.

(says no longer avail but just look up the new entry....likely video game companies complain and so they just keep switching company names.)

It's not that big a console so two adults are kinda snug side by side. If you don't care about vertical gaming, and track ball and plan on using with a TV, and sorting through a massive library and filler games...this is cheaper option with 4 times the games.
Joysticks and buttons are fully functionalable and replacing with Sanwa parts if needed later looks to be easy.
Cheapest way to get full nostalgia arcade and all the games I know of without the headache of building/ managing your own system.
