Ooo, you should definitely get a V1 the next chance you get though, especially if you see a good deal because those are getting harder to find! They're also fun to play with as well, really simple, almost like the vintages.
Have fun! I just ordered a V5 and V5.5 Familitchi. (As well as a V1, V2, V3, V4, V4.5, V6 and Tamagotchi Angel LOL) I'm very excited to start collecting!
