I'm gonna add two cents and then beg.
First the two cents. I've paid through the nose for a flies from a flyshop I really, really like. I think his flies are $0.25 or so more than other flyshops, and flyshops aren't cheap. I get a lot of flies there because the flies I get last all season, and even into the next. I've caught more fish than I can believe on a couple snowshoe rusty spinners. For all the use I got out of those flies and all the abuse they weathered, those were some amazingly cheap flies. Don't write off flyshops and local tyers, a good tie lasts. IMHO, it is a lot cheaper to buy flies than to tie your own, what with all the unused materials I have stacked and boxed and lost around my flytying bench.
Now the begging. Festus, for God's sake... Please, I am on my knees (OK, metaphorically... if I were actually on my knees, I'd be flat on the floor.) PLEASE DON'T POST PICTURES OF ANYTHING I TYE!!!
