I've had my Congo for over 7.5 years now and it would be one of the last pins to leave my collection if I was to ever downsize. I'm also glad I got it when it wasn't loved and paid $1640cdn too. This was also at the same time when Monster Bash was commanding $6000-6500. I was new to the hobby and hadn't been desensitized to the upper tier pricing (yet)
Monster Bash is a fun game and I always enjoy playing it in other people's collections but I couldn't justify dropping $9000-$12000 for it. However I might consider the new Monster Bash Remake Classic Edition since it is priced at $6k usd.
