Good post as I have the same problem!
Not to hijack, just curious where you buy your chain at $10??? My local place carries Oregon but they are all $25 give or take.
Here is an awesome tip I picked up elsewhere. Ask the manager of any local places that sharpen chains if they have abandoned chains, most places are sitting on a bunch of chain that no one has claimed past their policy period. Many times they will sell you a pile of saw chain very cheap just to clean out their shelves. One guy claimed to literally have gotten a box of chains for $20.
