You say new speedball player, are you new to electronic markers as well. If so I would not suggest your first one to be used and certainly not that old. If you end up having issues they could be harder to fix.
I could be biased though, I personally hate the idea of buying a used marker.
My spool experience causes a little discrimination I suppose.

NT: requires at least a four year degree in metallurgy, physics, meteorology and dark magic to get it to operate.
