Thanks for the info guys!
I haven't found any GBBs that I'm comfortable with trying, this TSD 1911 seems to be the front runner so far. It will have to wait for about a month since I have spent all I am allowing myself to spend this month by sending my brother some money to get me stuff from the Calgary Comic Expo since I won't be making it this time, and ordering a holster for a replica gun I just finished customizing so I need to let my account cool off before I burn through the rest of my savings that should be going towards a new computer for work!
I will keep looking in the meantime to see if I can find a GBB that fits the criteria. I hope you guys will have your memory jogged and post here if you think you find one that weighs about 1.5lbs and has that "classic" 1911 shape, and isn't over $100 shipped (I know, You can call me a cheap @$$ but I prefer "thrifty"!)
