3 Letter .org

I'd like to buy a 3L.org
Buying 1-2 such domains
Budget $350 per domain

I can consider 3 character .org domains with numbers if it's interesting enough, but obviously not at the same price range.

Payment - Atom lead, afternic, sedo, DAN, Paypal possible but with an invoice( I just need traceability for myself), not using FNF for this
