Rod info/advice

I read another post about a $100 T-rig, C-rig, Jig rod and it seems that Shimano Compre won out.  Where is the cheapest place to get one?

In researching rods I found the Compre has an IM8 rating and what seemed to be in the running on the other post Allstar rods has a rating of IM10.  Is this a standard that all rod makers follow?  If so then wouldn't the Allstar at 10 be better?  Allstar also has 3 different series of rods with this rating in the price range, any preference of the 3?

I have a lite action St. Croix premier rod that I really like for creek fishing.  What does everyone think of the Premiers in heavier action and how do they compare with the before mentioned rods?

I plan on buying a 7' MH F action.

Thanks again for all the info!
