Best brand or place for replacement coils

Is there a place to buy good replacement coils for old chainsaws? There are a lot on e-Bay . Is there one place better than the other. I want a good dependable Coil

 

I think ebay is probably the best overall. They are usually my first choice, before looking elsewhere. Your decision is whether to get a knockoff or a genuine replacement. There is usually a big difference in cost. You might get lucky and find a NOS unit there, at a decent price. It does happen.

 

I don't mine buy factory but they are hard to find for the old stuff. Thanks

 

That is an interesting idea for business as for me.
