I was doing taxes this weekend and pulled all the '18 receipts for my rebuild since I use the Burb for my side job. Machine work was about $1600. Everything else I spent ended up in the $1500 range. Some of those parts probably didn't need to be changed, but as long as everything else was going in new....... To do over again, I would probably buy a Jegs engine. But, at least I know my engine was done right. The biggest advantage I see to buying vs rebuilding is downtime would have been a few weeks instead of a few months.
