Price check on +1 Gem / +2 Fire Gem staff

So what is this worth? It's got the +1/+2 gem level combo and it has room for Casting speed or spell damage with Master crafting, but the other mods on it don't really help it out. I was looking on POE trade, and I was guessing that it would be somewhere in the single digit exalt range, but that's a pretty wide range.

This thing dropped for me the other night, and I'm giving it a whirl with flameblast. I'm curious to know how valuable it is though.
