(ET) Blades anyone?

[Stephen & Carol Welch <welches paonline com>]

Hi all,

Getting my deck going for the first time with new motor bearings, etc.  I 
am
finding an unpleasant rhythmic vibration (harmonic?) and am thinking I 
ought
to try new blades.  The old ones appear serviceable, but are not perfectly
straight and do have some gouges & wear.

Where do you get your blades?  Is there a modern equipment cross-reference?
I know some folks tried Gatorblades a couple of years ago - anyone still
using them with success?  If so which ones?

Thanks in advance - the grass is a growin'!
