As for that physical cabinet, it is fine. Arcadeshop is a legitimate company and it is put together decently, I have seen a few of them pop up at the auctions.
As for multicades in general....
Most of the people who build the multigames slap 8 way joysticks in there because they are largely putting together a "surprise, you just bought crap" product. Most multicade builds suffer the exact same problems that most Chinese products in general do, they are designed to look impressive and have impressive specs, but corners are cut so ridiculously in their construction that the resulting product is junk, even though spending 10 percent more would have made a great product.
The 60 in 1 board powering most of the multicades is a great example of what I am talking about. The games on it require 4 separate kinds of controllers, but almost every one I ever see for sale has a single one, an 8-way joystick 90 percent of the time, since that is cheaper than the Namco Reunion 4-way that should be installed in it instead.
If you build a PCB powered multicade project you need to stop listening to the tiny voice in your head that insists that more is always better. Every one I ever see for sale has all 60 games turned on, which guarantees that the people who play it will spend a significant amount of time playing things that don't control right or have distorted sound.
I myself turn off every game that is for the wrong kind of control or has distorted sound or other problems. When people play a multicade I built they are never stuck playing crap.
I have been out to quite a few houses to repair problems with various 60 in 1 machines (and the precursors to those boards) because the people who put them together seem to only care about extracting money from their customer and could care less if the customer enjoys the end product. Problems I have came out to fix include all the following.
Lots of games impossible to play because the cabinet only has one button (roughly half the games on the board require multiple buttons). I still see this on lots of them on craigslist.
Ms. Pac-Man impossible to control. 8-way joystick, combined with speedy pac and a high latency cheapo lcd tv made the one game this person bought the machine for unplayable.
Cocktail cabinet that didn't flip the game for player 2. This one is extra ridiculous as it was a turn-key premade cocktail cabinet that was sold with the 39 in 1 board already installed (a cheapo plexiglass copy of the midway cocktail with plastic control panels cranked out by a few different amusement companies). In fact, most of the times I have provided assistance with these machines is because the installer stuck the board in the cabinet and didn't configure anything (like cocktail mode or turning the volume to a decent level, or turning off the horrid looping attract music, or setting the speedy versions of the pac games to actually be the speedy versions (in another example of craptastic chinese factory quality control the speedy versions of the Pac games are set to slow by default).
