What is the best type of hooded hair dryer?

I am thinking about buying either a hard or soft type hooded hair dryer to dry my roller sets





Please note the dryer will need to be big enough to accomodate jumbo sized rollers as i sometimes set my hair in themWhat is the best type of hooded hair dryer?
Sally's beauty supply carries a soft hood dryer that will accommodate lg rollers, the hard hood dryers the accommodate the lg roller can be very expensive but if price is not an issue i would recommend a hard dryer you can place them behind any chair they work great for deep conditioning where as the soft dryer can be very hard to clean. Check you local papers sometimes you can find used dryers from salons going out of business or check with your local salon as to where to get used ones at a better price.
