@bel4_20 my response wasn't the best so let me respond a second time........
When looking online there are a bunch of WFO's. Some are kits and some are assembled. A lot of what you see is in the $5k - $10k range. Don't be discouraged there are more reasonably priced options (you just have to search around). Quite a few of us have WFO's even if we only post occasionally.
Some have the multi fuel table top ovens. Others have larger more traditional WFO's on rolling carts. Mine is one that needs to be installed on some type of support. I think mine is the most expensive of the lot (I could be wrong but if I am not by much). Mine was just shy of $2,500 delivered. I thought it was very reasonably priced compared to what's out there. Even $2,500 sounds expensive but not really compared to a Big Joe, XL Green Egg or XL Primo.
WFO's are fun and a challenge to properly tame live fire. You won't regret the purchase once you make the decision to pull the trigger.
