Welcome to the Escape world, Rumbac,
There are no used 21' models as they just started production. The wait list is almost 9 months but if you can convince someone to give up their $500 and spot in line, who knows. Otherwise you may have to wait until fall. You can see a 21 by contact ETI and requesting a viewing, they will put you in contact with someone near you. I'm aware of Escape 19's near you in Pennsylvania and a 21 is in Illinois.
never in doubt, often wrong
