I'm putting this thread here, because these items can power an assortment of types and scales.
I thought it might be interesting to see what types of units are being used/collected; I'll start with a few, then add more if there's any interest..
Flyer "15B"; nice unit which works great for 3 rail, Flyer and Standard Gauge. Looks cool, too! I like the "dead man's" feature as well...
Heathkit "RP-1065"; this will run any DC stuff as well as you can imagine, although it is a pretty lightweight pack. Great for smaller gauges and can-motored O scale.
Lionel Type R; nice little unit. I got this for my Standard Gauge, but it also works great on the workbench.
MRC "Dual Pack Model 1"; I got this for my 2 rail O scale. It's fine, although the rheostats are not super sensitive...
Last one for now:
This works great for postwar O and S, but the low end is a little too high (I think) for can motored O stuff.
Okay, your turn!
