Personally, I think rollers are for developing leg speed and pedal stroke. If you want to work on power or climbing, a stationary trainer is best. I use the basic Tacx rollers. When I lived in Michigan, they were a staple of my training. For power workouts, I bought a used Lemond Revmaster for $150 from place that sells gym equipment after it comes off the lease to the gyms. The Lemond is robust, weighs a couple hundred pounds, and is great for power efforts (and doesn't mess up your bike).
