I had a US console in the 90's, wish I had kept it. For nostalgia sake, I ended up getting European and Japanese consoles later on, changed the Euro console to NTSC. Both were finicky in one way or another, and what surprised me about them when I got them was just how cheap and light they felt. I seemed to remember a much more robust feeling, but memory is a funny thing, I guess.
In any case, I lost all my AES stuff in a drunken game of cribbage, so I decided to go down the MVS route and have not had any regrets. The only thing I wish was more accessible on MVS is the memory card. I have an MV2F board that will take a card, but it's rather large. And I have an MV1B board with a virtual memory card, but that has its limitations as well (such as certain games not giving you the option to not use a memory card unless you remove it, which ofc you can't so easily with a virtual one). Would love to see TimeHarvest update their AES-style clone to take an actual memory card, but probably won't happen.
