Hi;
Not Quite sure what you are asking about, but TBS has been around for some time, and there Conversions and kits are Nice but Expensive. As with all resin there are problems with Quality of Casting, As far as there PE sets go they seem to be on par with some of the other producers.
There kits are very Basic and require some work, so this conversion looks kind of Sparse on the Detail side for the resin included, as per the PE it looks like its pretty nice. From A personal stand-point; I really Don't like A lot of PE as I Don't think its really necessary. But thats just Me !
CHEERS; MIKE.
