I'd go to the local dive store and check-out the makes he carries and check-out his prices. Do some research, pick a reg that will suit your needs. I'd look at warranties and service plans as well.
Check-out what you can get a similar reg for used add about $100 and compare this with the cost of a new regulator purchased on the Web. Once you have the prices fixed for local purchase, Internet and used. Make your decision.
I wouldn't worry about purchasing anything used, but their is more to consider than just price. Personally, I haven't purchased a new regulator in over 30 years and have acquired them used for the right price. Knowing what you want is the greatest hurdle. Good luck!
