I guesstimate the parts for a what I would call a quality 6in f8 ota at over $1000usd and a premium ota at over $1500+usd. Lets say $450-$600 for the mirror $200-$450+ for a focuser, add a secondary, mirror cell, spider, tube, raci finder, rings, dovetail plus whatever else and the cost escalates.
The VX6L 1/10PV price, tax, shipping should be less than the quality parts price.
My other option would be a new Skywatcher (31010), Orion or GSO dob, with the new alt bearings, and obtain a quality optic that will drop in. I would still have a dob ota (I cant leave a particle board mount outside), and, I prefer a gem mount with tracking for my use. OO UK does make a nice looking metal dob base with cradle/rings (looks like it could be left outside with proper covering), but, due to tax and shipping on that, it may be cheaper to have a similar base fabricated in the US.
I do have a Hardin (GSO) 6in f8 dob, balanced with magnets, raci finder, ptfe, original optics (nice). I can use the ota on a gem, but, for a permanent mounting, the bearings get in the way, and it could use a upgrade imo. I plan to give the Hardin to a friend nearing retirement as his "first scope".
Just my reasoning, or lack thereof.
