Im sitting on like 300K gold right now and am thinking of getting 10 vial of the sands dragons but am wondering if there is a easy way to get a dragon mount, decent looking (probably not the bronze one) with level 80's?

I looked at the nether whatever quest and that looks super long. Then there is the rare spawn in LK which might be better. Any other ideas? Or maybe because I can have a rider the vial of sands one is the best.
