Hey!
I suggest the addon should respect reforge gold cost as secondary priority factor.
If a few reforge recommendations have the same weight, player should see the cheapest one.

Example

The addon suggested me to reforge two items (amongst the others):

1. 128 Crit -> Expertise
2. 128 Hit -> Crit

I reforged the second item from 128 Hit -> Expertise, got same stats and saved about 10 gold.

But it's an obvious replacement. I suppose there are more complicated ones, which player can't easily see.
