It really depends, my exotic veterinarian charges a flat rate of $65 for just the office visit and basic examination, she charged me an extra $25 for a handling fee when i brought my 13ft Burmese Python and my 4 1/2-5ft Nile Monitor in on two separate occassions a couple years ago, i guess it was due to their high strung attitudes and large size.
Obviously cost is always a factor but i would look more at the experience level of the veterinarian, that is the most important thing. Every office varies so much with prices that your best bet is to call around and ask.
