If you want to buy good quality sleep apnea equipment online, go to http://www.cpap-supply.com/ Is not cheap but is very good quality products.
The best one's I have come across have been the ones at Bed Bath and Beyond. Not too bad a price, the only issue is finding one you are comfortable wearing and keeping for a while.
