At $300, you have lots of great choices.....you'll want to narrow it down a bit.....laser, workhorse, clad, not clad, narrow, wide.....etc.
Here are some good $300(ish) gyuto's to ponder over:http://www.chefknivestogo.com/makswa24.html
Time proven, narrow profile, solid (not clad) gyuto. http://www.chefknivestogo.com/tanakagyuto1.html
Workhorse, damascus clad (not stainless damascus), little bit taller profilehttp://www.chefknivestogo.com/mayugy24.html
Stainless clad option.....great geometryhttp://www.chefknivestogo.com/taassala24gy.html
Still have love for Takeda.....I like the narrow profile "Sasanoha" option from him these days
