Yes it is a problem even for me. So far there is only one good cure that I have seen but it could lead to other problems. Step 1 stop working(no money to buy valks) step 2 give up watching Macross(this gets rid of the temptation) step 3 give up anime magazines(this too helps get rid of the temptation) step 4 and the most painfull give up Macrossworld and other internet Macross sites.(doing this could have undesired effects, withdraw, agressive behavior, suicide.)
I say with those in mind I would rather be a Valkoholic for life! Bring on the Yamato's. I even keep some at work. My boss knows I do more work with them on my desk.
