u got links for where to buy it and all the stuff i need?
I guess most people ordered from http://www.watdon.co.uk/wd-strings/
I suggest you give them a call, they are very knowledgable and helpful.
OBS! You might ask about a set of tools (with pliers, awl etc) since nothing was included when I ordered the machine.
You should check out this system 'All-metal true automatic true tension system' before placing your order for 'all-metal Linear Ball bearing string gripper' as on challenger 1.
'All-metal true automatic true tension system' save you big time, just need one pull.
