I, too, struggle with the charging systems required for my rechargable lights.
I have some low-powered lights that use NiMH or Li-Ion cells with I charge seperately.
I have a couple ROPs with 2D-to-6AA or 6A battery holders, which I charge outside the light in a cradle attached to a pack charger.
I hate using any of these because I don't like to fiddle with the chargers--which require plugs, table space, a safe place to operate, loose cells, multiple wall adaptors, etc. Some folks enjoy playing with rechargable lights, but I don't like the hassle. As a result, most of my rechargable-powered lights see little use.
I do, however, have two rechargable lights that see regular use: a MagCharger and an old Surefire 9N (not the 9AN). I love both of these lights because they use simple, elegant charging cradles. I don't have to remove the battery pack from the light. I don't even have to plug anything in. I just slip the light into the charger (which is also a convenient wall/dash mount) and go.
I keep the MagCharger mounted by the back door, plugged in via the plug adapter, and the 9N is mounted in the car running off the 12v line current.
I've read a lot of threads arguing that lights like this are best suited to be used as duty lights--drained and recharged every night. I agree that such is the primary, and best, use for these lights. Nonetheless, they have proved very useful for me. Neither is a primary light for me, but they are always there, and I can use them without worrying about the battery state. I have not noticed any ill effects to the batteries from being on the chargers all the time. Maybe I'm just lucky?
So, that's a long way of saying that I prefer a rechargable flashlight of the MagCharger/StrIon variety--built in contacts with a special charging cradle.
I've often thought of converting my MagCharger to an 1185 and modifying the charging base. Maybe I should consider upgrading the 9N to real hotwire status as well? I think I might be able to drill out the body (from the top) and make enough room for 2 Emoli cells and a spacer at the tail. You could gut the charger, and connect an appropriate pack charger to the contacts in the cradle. Of course, then I'd have to make an adapter from an old lamp assembly to host an 1111...and change the plastic lense... --But now I'm hijacking the thread. Sorry.
