I guess that most modern "shack-in-a-box" type rigs are capable of it, so there must be a moderate population of hams out there that you could talk to, but I doubt that many of them have ever operated AM... In my experience, 2m is fairly lightly populated these days and you need all the help you can get in order to make QSOs. Repeaters are not going to let AM through, so you are talking about simplex communication and the majority of modern transmitters are going to wind back the power as soon as you select AM!
