...it's definitely not an American V4) are most likely V2s because the only Connections without antennas are the V1s, V2s, and V6s. We know they're most likely not V6s because they all have musical designs and as for eliminating the V1s, I tend to think that they have more simpler designs and color schemes than the V2s. I don't memorize the designs of the V1s and V2s though, but this is my crude way, of sorts, to distinguish them. I don't know what the 2 bigger ones are. As for if it's a good deal, $30 seems to be good to me for 6 Tamagotchis.
You know what? I thought it was a V3 at first too because all I could see, even when enlarging the photo, is a small antenna on the left side, a characteristic of V3s. I looked up the sunflower design though and I don't think the V3 line seems to have it, only the V4s. The V4s have an antenna with a little ball at the top, similar to the one found on Entama/Uratama/etc. So that confused me a bit (maybe I'm just not familiar with all the shell designs), but once you receive them, that's how you can tell, by looking at the antenna.
:furawatchi: 
I'm don't think that is right though, I have never heard of anything such as a tamagotchi v1.2 and my v1 and v2 are just the same size...
