Here is my MN190 Mak-Newt that has a home-made dob base for visual use.
The base mostly made from leftover construction plywood and parts from other projects. But there is some new baltic birch in it as well and I did end up buying a lazy-susan bearing for the azimuth bearing.
To easily mount the scope in the base, I also bought an extra set of rings and used them instead of a tube holding box. That part works really well, I can mount and un-mount the tube from the base in under a minute without needing tools.
The rest of it ranges from pretty good to "still needs work". But I do use it regularly. It's great in the winter as a lug-and-go when it's too cold to bother setting up on of the EQ mounts. And it's also much easier to view with than an EQ mount.
The total cost, including rings and bearing was around $100.
