Assuming you sell the M2 (retails around $1300) for $500 and add the pocket burning $1000, you're basically back to the cost of the M2.
Contrary to the other recommendations, you'll need to drop over $1500 plus the proceeds of the M2 to make a significant upgrade which would be the likes of a Zyx Airy 2, Zyx Airy 3, Sumiko Celebration, Lyra Helikon, etc.
The Encounter is hardly an overachiever and sells for $1600+ not $2000.
