Anybody deal with member "Ronni"

FWIW...I've bought and sold plenty of parts on other forums using MO's and was fortunate enough to never get scammed. Having said that, now that I have PayPal, I wouldn't use a MO unless there were no other alternative. I know plenty of others that have been screwed royal and there is little or no recourse.
In the end, it's your choice...and your risk.
