Hey guys, I am rekindling my love for Lego but I am new to the world of MOCs and all the advances that have happened since I was 10... I am trying to figure out of it is economical to rebuild the MOC in the following links; http://www.brothers-brick.com/2009/12/24/microscale-colosseum/ http://www.brickshelf.com/cgi-bin/gallery.cgi?f=413598 Could someone give me an estimation on number of pieces required/cost? Also, any information you think I might need (assume that I am relatively ignorant when it comes to Lego) Any help would be appreciated greatly!!

Hey guys, do you know approx. how many pieces this MOC would have used? I am wondering whether it would be economical to reproduce it?? Cheers!
