I currently have a DM13 and have had it for about a month now. On its day it has been amazing and shot ropes but in the cold and wet weather we have been getting lately it hasn't been performing well at all. What I want to know is should I keep the DM13 and hope for better weather or sell it and buy a GEO 3. Really I am looking for a reliable marker for no more than £500, new or used, and not an AXE though.
