sasha you must have been lucky, as i did deal with him and have seen more of his bad work than his good work.
the one thing with this forum is that not everyone likes to complain, especially when its a well known trader, i know several people who have had bad jobs done but never said anything.
its a shame as i think sometimes there can be an unbalanced view of things which can result in more people loosing money when they shouldn't have too. and when anything bad is said all the coat tail clingers pipe up to defend their trader. but thats life i suppose.
my advice is choose your trader carefully, do your research, pm long standing members and ask for reccomendations, the mod team as a colaboration all have expeirence of pretty much all traders and should be able to guide you in the right direction.
also find other members who have had theo work done that you want and see where they bought it from/had it done. same as getting a building quote. speak to more than one person. get a balanced view.
