Intro
I get a lot of questions regarding the legitimacy of current companies in the marketplace. Its not always viable for customers to search through 1000 pages of drama and so I've assembled the below summary of current market suppliers. Remember, this information is my personal interpretation of past performance and it is NOT an absolute indicator of what will happen to your order. Supplement this guide with your own research, protect your money.

Rating System
Position in the list signifies trustworthiness, the higher the better. A perfect score is 100 and the worst possible score is 10. Criteria includes the use of preorders, prompt delivery, the investment of custom chips, hardware and refund issues, communication ability, ethical behaviour and company size.
   90+ = AAA tier firm
   80+ = A tier firm
   70+ = B tier firm, company can improve practises
   50+ = C tier firm, issues to be resolved
   30+ = D tier firm, significant issues or problems
   30- = E tier firm
