Anco...seriously. Best ones I have ever bought, and they were like $7 for each complete blade (not inserts).
I used to use Bosch, thinking because they were Bosch they had to be better. When the last pair actually fell apart after a year (inserts starting tearing), I went to the store for replacements. The only Bosch's in my size looked weird...the newer aero style or whatever, plus they were expensive. The only normal, OEM looking blades were the Ancos at $7 each. I bought those and they are still working GREAT after a year. No smearing or streaking. I have wiped them off with a wet rag maybe twice. I probably won't be buying Bosch again.
