Vance fwiw I would put this d bag on ignor, no trees, except for what he got ripped off for, and not much in the way of good info, and believe him he's patting hisself on the back.
Atilla, yamadori can't count in a discussion such as this, by Mystos statements not at all, or at best just as bad as nursery materials, no good roots, not pruned over the years, he gets it both ways.
"specifically the horticultural processes you use shifting root bound garden center stock into progressable bonsai--especially your work with mugos....sigh." - go find someone that has offered as much of this info out there and you are doing well, and it is a huge chunk of bonsai.
Johng seriously, still got a bee in your bonnet a year after seeing something you didn't like, and if Vance got it right on the thread then you need more help then you will get here.
Vance, you have pretty much been nothing less than a mentor to many more than you will ever know, keep up the good work and words, there are MANY here and others in and out that appreciate the time you spend here. We are better for it, and get it.
By the way leaving out the shyte expensive trees sold on ebay, there are a lot of $400-500 nothing but stumps that need to be grown and carved, being sold as quality pre bonsai, that unless you have talent or dumb luck will probably not amount to what a cheap Home Depot tree may. Is it worth more, yes but only due to time spent growing it fat, and not much else.
