Possibly even lower

If it was 30% Movement speed AND 25% Inc Effect, then it'd be like 150-500fg (sellable price)

I bought a flask recently similar to that as a crafting base and it cost me 7.5ex or 37.5fg

People price fix but you could probably get 75fg if you sell it in game first for 15 exalted

Not much. What your looking for is +6 max res in addition to those stats

i think the more important stat is 25% iiq
