I have been trying my best to resist GAS unless I really need something but that's easier said than done!
I have ticked off one item already (EZ Drummer 2) and only have a few others on the list

I hear ya! That EZDrummer looks like the best way to write a drum track, for us non-drummers especially!  I have been looking at that for a while, but not in a rush.  I would like to find a really good deal first.  I would like to hear your thoughts on it after you have used it for a while.
 
Beyond that, I think I am pretty well set for synths and effects plugins.  Trying to learn better what I have on hand already, LOL!  The exception to that may be a good u-he synth.  I have been running several demos of their top synths for ages, and they are tugging at me.  But the good thing is sales and discounts are very rare in that arena, and for good reason!  Maybe the buy and sell forum at KVR is the place to go for that!
