Nice"true" classic Leo's with big spots are already harder to get than BDs imo,sure the BD craze is justified but lets not forget just how nice a top quality Classic can be,black rays with fewer but massive spots do it for me every time.
Regarding price i would say you could pic up an average classic for say £350-£400 in the current economic climate(privately) but would expect that figure to rise somewhat for an exceptional fish with huge round spots.
I would take a quality Classic over an average BD any day of the week.
rayrayray has some due imminently,parents are very nice so the pups should turn out even better.
