What are you wanting to use the 60-75 for? One particular animal or do you have possibly more than one kind of animal in mind?
I would wait and mean while search. That is a lot of money when maybe you could search on local selling sites and find something used that the seller doesn't need anymore at a lot cheaper price. Does the tank you want have to be brand new? Does it have to be a glass tank, what about what the others are saying about PVC?
I would wait and see what the next Repticon has too offer you can always go back to the pet store. I doubt the price will go up much since it is already pretty high.
