Remember everything you read is filtered through preconceptions.
In someone else's eyes, its wrong - possibly including your eyes.

How many crap builds and half finished, or even half-started builds are out there?

So I suggest that to people interested in buying right, first time, to do the intended job, the uncertainty hinted at in a conversion is exactly what they are not looking for.

To the rest of us, eg with half-rebuilt planes in the garage and a backlog of interesting gun projects, these are a way to participate in the DR world that challenges our technical interest. Like any such sphere of endeavour we expect a spectrum of quality in inputs - and outputs.

For 'affordable range' DR buyers, the conversion is a potential money pit, only justified because we can - or maybe we can, one day. Far better to run a lemonade stall and buy a known good one out of the profits if we want certainty of results.
