15mm-ish metal helos at Wal-Mart for $1.99

Score.	The AH-64a is just shy of 5", so by my figgerin' it's about
1/140 or so, with true 15mm being 1/118 or so.	These babies were
under $2.00 ($1.99, IIRC).

Main body is die cast metal, with soft plastic rotors and accessories.
The scan isn't great, but it's Maisto Tailwinds, Series IV.  There are
several airplanes, and the two helicopters are "AH-64A" and "UH-60A
Desert Hawk."  All are numbered "#15061."

I'm sold on these-- my plastic kits tend to break, as I typically just
throw them in a box or the closet or somesuch.
