Agreed - that's a HUGE pet peeve for me (click the link in my signature about "cheap")- using the work cheap when talking about a living animal. I would choose "most affordable".
The word cheap just "cheapens" the animal.
I personally shop the snake, not the price. You can find some really ugly pastel males for as low as $40. Or - you can pay a lot more for the best example that you can find - if your plan is to breed.
If it's just for a pet and you want to simply own one - go for the the lowest priced, lower quality critter if price is the primary driver.
