What would be a smooth high end marker that doesnt require a TON of maintainence
and dont some of those used markers have problems????
Just make sure you are smart when buying - ask them about any previous problems and make sure you get a video of the marker shooting 300 FPS and showing that it does not have any leaks, etc. You should not have any problems with buying used as long as you go about it the right way and buy from a trusted seller.
