126 car top carrier?
 

My son has to bring his guitar on vacation this year so we need more space than the trunk has.

Has anyone used a car top carrier for a 126? What brand?

I'd rather not spen the money on a Thule or Saris and then still have to buy a case - we'll only use this rarely. The Sears x-cargo clips won't fit - are there other carriers they folks have used that work?
