You can look at this two ways, 1. You can make a custom pit to your exact specs or 2. Buy one that is close enough. That is the difference in the cost. More on reddit.com

My experience is that on Reddit when you ask questions like this, you get answers that are all over the board and it gets difficult to decide what you REALLY need to do. I wanted a fire pit and ran into the same warnings. Here's what I did. Can't tell you if it's right for you or not. I live where there's no danger of me starting some kind of underground fire ... water tables too high and it rains too much. I picked a place not under any trees I wanted to keep and cleared away the grass. I'm a cheap bastard. I read all the shit about exploding bricks. I went with these. . Dry laid them directly on the ground up to five courses high. Thirteen blocks to a course gave me a 24 inch interior area. I even went up-town hipster and put in a pipe underground to supply air to the fire when ash began to build up. Then I poured a bag of sand over the bottom inside. I've used it for years. Nothings ever exploded. Exactly two bricks have cracked and those two happened on the same night when a large diameter hardwood log was left resting directly on top of those bricks burning all night. I've burned hardwood fires in it for hours involving drinks, cooking meals, roasted-marshmallows, and shooting the shit afterwards... Hours ....and then covered it an let the rest of the fire burn out over night. Never a problem. Now.... I recommend that you don't do what I did 'cause everyone's gonna tell you that it's dangerous. But me? I took all the money I didn't spend and bought a nice bottle of single-malt. Goes good with a nice fire and a woman that loves you. More on reddit.com
