With regular maintenance id say buy the gear. how much is your safety worth? the gear at many of the places i've visited outside of the United States were in poor condition at best bcs held together with zip ties, and regs with no ziptie on the mouthpiece and broken consoles. If you can afford it buy good used gear and keep up on the maintenance that way you know your gear and know what to look for if there is a problem. I would purchase, reg computer then bc in that order.
+1 It's YOUR life..how much is it worth? Buy new and maintain....
