I use Probemas because it's easy, safe, has an AWESOME staff that's transparent about all questions and concerns i've ever had, and has virtually no-ban rate (from my own reading of reviews and personal exp.) I'm at Rune rank, but I still give it 4/5, because it could be better as far as pricing goes. They say they run through based on the market, but the market has always crashed and fluctuated, so there isn't an ACTUAL reason to make the prices any more expensive than $0.50/M. Moreover; the service could be quicker by simply adding a part-time worker into the shift to assist during the busiest hours.
