There's the ones shaped like Digivices that come out for anniversaries that cost a fuckton, but the more standard V-Pets are more common.
Your current choices are-
>20th Anniversary Edition
Best bang for your buck, about $20 on Amazon, has something like 150 different digimon in it. Downside is that Amazon only has them in Glow in the Dark, which is still pretty cool
>Vital Bracelet
Upside is that it has a bunch of different expansion chips(including a Medabots crossover), downside is that it's a wrist nag, and you'll probably have to find 3rd party straps since it's designed for Japanese Children.
>Xros Wars 10th Anniversary
Upside is that it's coming out soon and in Color, downside is that it's ENTIRELY Shoutmon evolutions.
>25th Anniversary Edition
Downside is that it has a much smaller roster than the 20th, which jammed each version of the first line in one device, where this has 5 like the OG. Upside is that it's in color and includes Mega levels.
>Monster Hunter crossover
Upside is that it's pretty cool if you like MonHun, downside is that it's less common and more expensive
>Godzilla Crossover Edition
Downside is that it's rare, expensive, popular for a v-pet, and you're late to the party. Has 2 versions, Greymon and Machinedramon
Upside is that it's color, and there's a second wave coming out in the Pendulum Editions, the ones that shake when you walk or just jack off with it. Also Pre-orders haven't opened yet, so your chances are good if you want to pay that much for it.
There's more options, but that's a good start, and almost all of them are compatible with each other for fights.
