I bought a new road bike bike from PlanetX a couple of years back, and I found the shallow drop handlebars it came with so comfortable I got another set for one of my other road bikes.

I like the fact that when you go down on the drops, it's not such a big drop as it were, so you don't feel as if you're Mark Cavendish entering the final 100M of a sprint stage with your nose on the front tyre and your arse in the air. They're quite comfortable - useful if you're battling into a headwind as you get a bit lower, but not too low so that it's uncomfortable.
Also, the bars have sufficient "bend" on them that when you set the top of the bars parallel to the ground, the drops are also closer to being horizontal as well. I found my other bars uncomfortable when on the drops because the bit you're holding on to is at too steep an angle, rather than almost horizontal. Other people will be more comfortable the other way round though, so it depends what suite you best.
I also went for a wider bar than was recommended for my size, going for a 44cm width rather than 42cm (I'm 6ft 2in tall, with a 44 inch chest). At my age I'm more interested in being comfortable rather than having a more areodynamic profile, and the extra bit of width suits me better and I feel more comfortable. I certainly notice the difference when I ride a bike with less width on the bar.
Finally, at 20 quid it's not the end of the world if you don't like the bar and want to change it again.
Hope that helps a bit
