While I use SBCL, CCL, and CLisp for free I also paid for the $3100 professional LispWork license and pay the yearly maintenance fee.
Recently, LispWorks stopped running when I updated my M1 MacBook so I had to just use other implementations for a short while until LispWorks gave me a custom built beta. They really do provide good service.
If this seems expensive, in 1982 I got a Xerox 1108 Lisp Machine that cost $25K, which is about $72K in 2021 dollars. Sometimes good tools cost money.
