Looking for some of your thoughts on David Perron.

I have a chance to acquire him in my dynasty league and I want to know what your thoughts are in terms of his long term potential. 

Only G and A matter in my league keep in mind.

What would a reasonable price be?  Trying to avoid dealing any of my picks, looking just to move spare parts.  For example people I might move would be Erat, S. Kostitsyn, Stafford, W. Simmonds.

I know he's looking for immediate help that can out produce Perron as he is trying to make our playoffs.  And to be honest, so am I.

I can list more of my assets in the comments if need be - cause our rosters are fairly deep
