The good old, pain in the bottom sought after versus rare situation. There are quite a lot of g3s that really do not pop up too often at all, but they are also not all that sought after by collectors (perhaps they were very common when released, had multiple versions or were just not that unique in design) so it keeps their prices low but makes them hard to find!
These 2 girls are not too bad. I agree they can be on the harder side to track down but they should not be too bad. I guess a little bad timing is perhaps a factor here. Have you perhaps tried an advert inyour signature?
