Depends on species. For Indos which are still being imported as WC, you could get one about no higher than $250 in the US. There are Indos that are occasionally captive bred and born here like mine. I got mine for $250. For Northerns, they cost more due to higher demand and they only have a litter of very limited number of babies per year, so you could be looking at about $300 and up depending on availability. These are all 100% CBB.
I guess price is subjective depending on one's budget. I look at the bigger picture: the enclosure plus UVB fixture and light cost a whole lot more than the lizard. I bought a discounted reef tank (125 gallon, 4 x 2) for about $300, the. reprising 10.0 T8 fixture was about $70 (T8 is good for no screen lid or very opened space screen like I have. Otherwise a T5 us recommended which runs around $80) and the bulb is about $20. The initial vet bill with fecal is a joke compared to what you need at start up.
