I picked up a 10 inch strikemaster flight from Wholesale sports about 4 years ago now for $100. Also got 2 - 8"lasermag augers for $268 each ......but of course Wholesales sports never had any sales no wonder why they went out of business
.
Sounds like this distributor might be the best bet or checking with fishing world or maybe even bass pro. Although sounds like you might have a auger blade issue and not a bent flight at all. Laser blades are extremely precise and even a slight dulling can make a huge difference.
Its mind boggling that no one here sells a full line of strikemaster or otter.
