How often do you find yourself buying Transformer stuff that maybe you don't really want or need, or probably shouldn't buy it now because of certain finances--BUT, you know that if you don't get it now, it's only going to go up in price later. And I don't mean for those who buy it for that value..to be resold when it goes up--I mean to have, keep, open, part of your collection etc..Even though you don't really need/want it right now..it's better to get now at initial cost, more so than wanting it needing it later, after it's gone up.. And if you have..what's been the biggest one you've done like that? And what's the one that you regret waiting on? My 2 regrets right now are for the BAPE G1 GREEN Optimus Prime which I've still yet to get..and then the 24" Sideshow Optimus Prime which I missed out on when it was 1100$ and now it's up towards 3000$ (fortunately I got one, and for only 1600$...but still would have preferred the 1100$) The one I'm debating right now is the new chromed jetwing buster Prime..189$ now...or in a few months will it be up in the 300$ or so? What to do what to do..
