Upgrading Aerogear Guide

It's cheaper to buy the 5 gold mount and use wind widgets to upgrade it than buying the prettier ones.

Why?
The 5 Gold Flying mounts start off at a speed of 1.00/3.00.
Every upgrade increases it by .50 so to max it you would need to go through all four upgrades.

• 1st upgrade 1.50/3.50 - 20 widgets
• 2nd upgrade 2.00/4.00 - 60 widgets
• 3rd upgrade 2.50/4.50 - 80 widgets
• 4th upgrade 3.00/5.00 - 80 widgets

Wind widgets are 10 silver ea. or 90 silver for a 10 pack.
So given this information the cost of upgrades would be

• 1st upgrade - 1 gold 80 silver
• 2nd upgrade - 5 gold 40 silver
• 3rd upgrade - 7 gold 20sliver
• 4th upgrade(Final) - 7 gold 20 silver
• Total upgrade cost is 21.60 gold + the cost of the mount = 26.60 gold

But what if I don't like the 5 gold mount? What if i want to buy the other cooler looking mounts?
