Saw building on forums can involve international transactions where sending saws back and forth is not really a feasable option. I think fairly calling out those who have known bad work or a number of bad dealings is looking after the community. Bad work is bad work, theft is theft simple as that. Ebay and other sites have a rating system and feedback one can go by, choosing a reptuable builder takes time and is not so simple. Their is only a small few I have complete faith in, I can't afford to gamble with my hard earned and have seen plenty of good folks been taken for a ride.
