Yes, I have one. Though I only got it this month from Suruga-ya via FromJapan. See the importing thread.
TBH I’ve played more games using the emulator over the last few years than I ever will on the hardware itself, but I just had to use one IRL to get the full impression. It’s 20 year old technology, so it’s not as enjoyable to play as modern devices: screen (ghosting), buttons (clicky/poor), storage capacity (loading new games gets old fast), battery life (going through lots of AA cells gives me nightmares) are all showing their age. Emulator with joypad is much more enjoyable for me.
Since my blog post went live all-bar-one of the other devices that were on sale are now sold, so there are a few people who have bought them since. Only one person has reached out to me about buying, so I guess the rest have been bought by collectors.
