I have cast-iron ones and they're great

as well as they're well-seasoned, nothing sticks

Just get them pre-seasoned and then just make sure you grease them well so they stay good and seasoned

They're wonderful!
You can get six-hole ones all over the place -
www.lehmans.com has them I know. I have to sets of six and two sets of 11-hole, that I got online from shoppers choice.com (or something...), I paid $13 each plus $8 s/h..
11-hole ones on shppers choice:
