Re:
I've had the same challenge.
I ended up buying new disc forks and v lowers and swapping them out, as this allowed me to get the best fork I could for a v brake build. Also had to adjust travel while I was at it.
I did this for a set of fox factory rlc fit forks which I still have and have done less than 10 miles on.
Another route I have taken is to buy all the parts needed to build the fork I wanted (in this case a rock shox sid world cup, with v lowers).
Last but not least and similar to the fox option, but using used, not new forks and lowers was a set of reba world cups. Originally disc only lowers but I swapped out to v versions. Serviced the internals, new oil, o-rings etc. Ended up with a very nice fork, though have sold the build after literally no miles (was a project to build a top spec bike from my spares bin for fun).
I did also recently buy a set of pace rc39 with v mounts. I ideally wanted rc41s but apparently they never did these with v mounts.
