I read up on rollers a couple of years ago when I was thinking about them vs a stationary trainer. One interesting idea was to set them up in a doorway at first so you could grab the door jams if needed while you were learning. I ultimately went with a Cyclops mag trainer but I did use that doorway technique one winter when I taught myself to track stand a FW bike.
I went with the stationary since I knew I'd get really bored and loose concentration and would crash off the rollers. I can also do one legged exercises which I didn't think could be done on rollers. I hot-rodded the mag trainer a bit to ensure it would provide more drag than I could overcome. Its worked out real well. Tough, quiet and adjustable.
