How do you collect your MH dolls?

[Yun]

I used to want to get them all, I did so until the first Gloom Beach line (not the multi-pack) and then I decided I had to stop... I still managed to complete the second dotd badge, but then I couldn't find classroom Lagoona and decided to just drop it... Since the dolls are really overpriced over here and I'm too lazy to buy them online (or they're just as overpriced online)
I now try to just buy the basic version of each character and if I really like another version, I'll get that one, but I've given up hope on collecting them all.
