WTT: My Castle 1520 for your 1518
 

Long story short, I ordered a 1520 from the Castle sale, and on second thought decided a 1518 would really be better for my application. I emailed Castle right away, but they said the order was already processed and they couldn't change.

If there is a chance anyone bought one of the 1518 and wants a 1520 instead let me know and we can trade. Thanks!
