Radios to fit dummy MBITR?`

[Fenrisianspirit]

So I'm looking to sort myself out with a set of comms for my Devgru loadout but don't want to spend a small fortune on a working replica MBITR only to have issues with it.

So the current plan is a set of Comtacs with a ptt. Now I've read that motorola talkabouts will fit in MBITR cases but which ones? Just want to make sure I pick up a suitable radio with minimum modding of the dummy needed. I'll readily consider a different brand of radio so long as the PTT is easy to acquire.

Cheers.
