Technobit gets a 10 on ethics? Has he ever read
https://bitcointalk.org/index.php?topic=682105 about the minion boards? Sure it's a bobsag-started thread, but that was just facilitating a group deal which minersource was also a customer of. Technobit's only six months late delivering on probably hundreds of boards (while continuing to do business on other things, make new products while ignoring existing customers...), and minersource probably lost more money on that shaft than anyone else.
There is PLENTY more available on technobit outright fraud but Dogie I guess is a paid spokesmen for them as well given that rating seems to be a few of those type ratings in his guide. Minersource to my knowledge has also defrauded at least one other fabricator like the claim black arrow made and have as Gleb said left a trail of broken contracts beyond what you read in these forums typically. Do not deal with either company. Further just avoid Dogie's hardware guide too many inconsistencies with regards to turning a blind eye to fraud or lack of ethics.
