That is a pretty reasonable price for this time of year. Around now a lot of people are beginning to pair and the proven females tend to get a little scarce and subsequently go up in price. I have picked up proven females for 25.00 on RARE occasion but have also seen really big girls go for 275.00 to 300.00 so 100.00 for a proven female this time of year is pretty reasonable IMO. As for breeder morphs that's a crap shoot too. I would say especially this time of year they will be hard to come by for that price. You may find a pastel or spider girl that's breedable but I would think it to be a bit of a long shot. Expos are funny though I have seen animals at all ends of the spectrum. I have seen a male breeder pied for 400.00 and a hatchling spider girl at 350.00!! And that was just this year. That's kind of the fun of the expo I guess it's kind of a gamble. IMO and only my opinion I would say go for the proven girl if she can fit your breeding needs this year. Hope this helps. Sorry to ramble
