I was considering the Chronicles trades, but was kind of turned off with them only including 6 issues

I'm not a hge Gil Kane fan. My favorite work from him is when he teamed with John Romita on Spider-Man, but I like his work on GL. At least he wasn't doing the up the nose shots.
And I agree with Todd on the costumes Kane devised. Green Lantern's costume has always been one of my favorites from DC. Thats why I miss the color with the Showcase. That dark green really makes his costume come to life!
