I think IEM's are great if the board (plenty of sends) and PA (self explanatory) can handle it. The last band I was in was starting to use a PreSonus board, a MacBook Pro and an Airport Express to do FOH and monitors. Everyone uses an iPad and with a free app and access to the wireless network you can pull up and set your own IEM mix. Actually, you could run FOH as well. Very cool.
If something like that isn't available, I like to have a small amp. I use a Genz Benz Shuttle 3.0-10T combo with a 110 Shuttle extension cab. Plenty of stage/house volume for my gigs. If I need more, there's a PA. I still set my amp up just t be sure I can hear. It's like 30 pounds divided into a couple 12" square boxes. Even my declining back can handle it.
I have also started working out again - one of those balance balls. It really helps.
