Just remeamber crafting costs are 1/3 the true values and rogues have a talent that further reduces that cost by 75%. Meaning a pit trap can cost around 62g common pit trap CR 1. Just don't forget all crafting rules, that 1000g is base price and/or that 250g.
Also I was thinking of a rules for booby traps just that do very little and have no higher CR than say 3-4 that cost only 100g per CR, but they are extremly simple traps that have little effect on the enemy. Just saying.
