MHBP-Aetna question

We switched from BCBS to MHBP-Aetna in November. We found only one provider in our area for CPAP supplies and they are horrible. Definitely not opposed to ordering online. Insurance company did not have a list of online CPAP equipment providers but just a list of companies that provide durable medical equipment. The list pretty much looks like wheelchairs, breast pumps etc and not CPAP supplies. Can anyone on MHBP recommend a great CPAP supply company? Really makes us want to go back to BCBS but the premiums are just crazy.
