Modeling for the tabletop

[raketenjagdpanzer]

Hey guys,

Some friends asked me to run a T2k game for them here, and I wasn't going to start until after the 1st of the year or so, which would give me time to get miniatures and such together. I've found some great resources for normal vehicles of the era, and indeed I have a 1/72 scale paper craft LAV-25 to put together, but what I'd really like to do is kitbash a LAV-75A4 (LAV-105).

The easiest approach as I can tell would be to get a 1/72 M113 kit and use the tracks and suspension, then a Stryker MGS kit to use the turret and bits from both to detail the hull, which I'd carve from balsa wood.

Thing is, maybe I'm going crazy but I cannot for the life of me find an M113 kit that doesn't cost a small fortune (to take the suspension/tracks from).

I've looked at papercraft stuff for the hull, I've looked high and low and keep hitting dead ends. Any suggestions?
