I’ve been using one for several years now with one of the documented switches that add multiple ports. https://docs.pikvm.org/ezcoo/#connections First in a DIY and then with the v3 hat Kickstarter I guess total I’m at $270 between the Kickstarter HAT and ezcoo switch plus the cost of a Pi (which I already had) I can reach 4 machines over my Tailnet and jump between them reliably. I can also control power on my primary server. (others are on a network managed PDU and can be forcibly reset that way if needed)

I had an old console from a job but it was so old that it required an ancient version of Java to access through the web interface. I’m sure there may be better options, but for my homelab setup the pikvm has worked well at a price that fit in my budget.
