I would not pay that money at all for those weights! I have seen 300 gram females (nice looking!) go for a 100 bucks a pop. And DEFINITELY would not pay $200 for any male that is not... very good looking... full grown... 100% healthy. IMO holding off and going to the show would be your best bet. G'luck!
EDIT: GEEZ! I was going to be the first poster... but by the time I finished 3 others got there first!!
