We used Dapper Ducts, and it was a lower price and they did a decent job. He showed me the junk they were vacuuming out -- we even found a contractor's screwdriver and wallboard scraps in teh ducts.
I used Dapper Ducts also and paid around $800, totally worth it as both our a/c units and all the vents were full of mold. I realize this industry has a terrible reputation and I would never do this annually, but it had never been done in 14 years so it was time. Totally recommend them. Price varies according to how many vents you have - we only have one in each room so I think we were on the cheaper side.
