The last show I went to regular crawellis were around 15, albino crawellis were 20-30 and ornates were around 30. You can expect to pay more for rarer colors, like lime green crawellis and high red ornates. Also harder to find species, such as cornutas and caatingas, would be more expensive, if they are available. Hope this helps. You will find good deals at the shows, just make sure the frogs are healthy and the dealer knows what they are doing.
