Hahah, just joking.  But dont laugh...I've 
thought about it...

No, actually, it's a matter of being in the right 
place at the right time.  YJ is very good for 
rare items too, and it's not cheapest, but it's 
very easy if you get to it in time, and use a 
great service to help out, like Celga, or Sato-
san.  Most people I think just try to catch the 
updates...and it helps to get cozy with fellow 
collectors with the same interests too.  That way 
you can help eachother out in the future :)...oh 
yes, did I mention Ebay?  Everyone hates 
them....but they've done quite well for me!
