Coil pack

[Matt Zajac <MTZajac@beloit.com>]

Hi good list people.
Quick question here. 
Have any of you had to replace coil pack recently ?
Where did you get it ?
$$ ?
Are there any aftermarket ones with either price or performance advantage over stock ones?
Last time I checked with the stealership they were about $400 here in Chicago. 
And haven't really hear about any aftermarket ones, maybe you can shed a little light on my dark cloudy head.
Thanks in advance.
