Hey Patterson,
The 3m is valued at over $300 new, If it is in good nick, I wouldn't let it go for anything less than $180. These are awesome trainers and pull like trucks. They include safety leash and quality lines etc. The 3m is nothing like the 2m it flies like a
real kite!
There are plenty of peeps who would gladly give you $180 I am sure. If not, I'll but it off you for $100 and sell it for a tidy profit.

Good winds,
