Yes. The supply has dried up so $90 isn't a bad price these days. If you want one, waiting will only make things worse lol.
I have a bunch of Micros, DS Lites, and even SP-101s but my go to is the backlit OG GBA. There's a few reasons... I prefer the form factor and find it much more comfortable to hold over long periods of time, it takes AAs so no worries about charging or replacing the battery in the future, screen is bigger than the Micro, and it has a headphone jack unlike the SP (though it's not great quality compared to the Lite I must concede). The DS Lite is probably a close second but I'm not fond of the button layout for GBA games in particular. Backlit OG GBA is not a must for everyone, but for me it's my favourite by far.
