If you're used to modern power steering you'll probably find it pretty heavy going without! Being a stick-armed girl I waited to find a car with it to be honest.
The downside is it's more to go wrong with the car in the future, if you were using second hand parts expect them to fail and need replacing.
Nowadays as I'm not driving the car as a daily given the choice I'd probably opt for no power steering as I no longer need to do lots of parking/spinning round supermarket car parks that kind of thing where you value the PS.
