I agree w/ ToddZ that nothing takes the place of the road, but there's a LONG off season here in Wisconsin. My friends who used to race in the 70s say that rollers are really the way to go for indoor training, since you have to use all your balancing muscles, etc., just like road riding. I've never tried that, but I have gone through a couple of magnetic wind trainers, none of which I was happy with. But last year I came across the Kurt Kinetic.
You'll choke at the price ... $300 for the "standard" model and $340 for the one with the larger, heavier flywheel ... but (as far as I can tell) it's the last trainer you'll have to buy. I LOVE mine, as much as you can love riding indoors in the winter time, and I really noticed a huge difference on my first couple of rides in the spring. Sure ... you still have to get in shape for the road, but the Kinetic really gives you a jump start.
I bit the bullet and went for the more expensive one, even though I'm a smaller guy (around 160lbs) ... folks on the discussion boards seemed to think the larger flywheel gave a more "road like" ride. I'm not disappointed ... couldn't be happier. The thing about this trainer is that it's REALLY heavy duty, so it's very stable. Doesn't move around very much at all. And the well designed quick release system makes it a breeze to get your bike on and off the trainer, in case you get a nice day in January.
Check it out at the Spinervals site:

Same price at both places. The spinervals site has a link to one review, but I'm sure you can find lots of folks talking about the Kinetic if you do a quick Google.
Ah ... here are a couple of pretty fair reviews:
