I collect G2s and I'd say you did very well on those prices (UDS, right?) for MOC ponies! Secret Tale is probably the most common considering she was released here in the US, too but that's still a good price. Since I'm in the US, most of my MOC come from overseas so I have to factor in quite a bit of shipping and would usually have to pay about double that for a MOC pony. So, IMO, you did great!
