Any one have experience using CPAP? Need some help here..

Although this is slightly off-topic, I am aware that a number of you suffer from sleep apnea. I had been diagnosed with minor sleep apnea that required no treatment a long time ago. My physician advised a CPAP machine when I was re-tested and the results revealed that I have mild sleep apnea. I've made plans to get everything set up and ready in July. I'm just wondering if anyone here has any suggestions and if anyone knows of an internet site for sleep apnea supplies. I travel a lot for business, including a medium-term trip the week after I get my CPAP, so I've had a lot of questions about that.
