Out of the 7 saws, this is the most picked out of the collection. The power to weight on this saw in best in its 50cc class. Such a quick, powerful, and lightweight saw. Echo's latest X series saws are built incredibly well. Sawsuppliers is my go to for echo saws and suppliers. I've bought a 2511T, 501P, 620PW, and 7310 from them and they have been phenomenal to work with.
