I really hope to get started on a build of it shortly. I've always been a big fan of the Esci kits, even with the shortcomings, but this one may have just surpassed them. I am surprised that none of the model companies have attempted to use the M113 at a platform for some of the other common variants in 1/72. Like a M577. Twenty years ago, my first attempts at scratchbuilding were a M35 guntruck converted froma Hasegawa GMC, a M557 converted from an Esci M113, and a M728 CEV. Never quite finished any of them as I went through a series of moves and ran out of steam.
I was disappointed that it seemed like Trumpeter and Dragon had several busy and promising years of Braille scale releases, but 2009 is slow and 2010 is slower. I am glad for what has been released (and haven't kept up with the build to buy ratio), but would like to see some of the armored cars that have been issued in 1/35 see production in 1/72 as well.
I generally build modern (Vietnam and later) vehicles. but have started to dabble in earlier ones.
