Chainsaw Repair

1st post, I somehow failed to add oil to my 2 cycle gas can and destroyed my new MS 271 cylinder and piston. 

The local Stihl dealer wants about $300 to replace the cylinder and piston, seems excessive.

I  am able to find an aftermarket piston for about $30 bucks, but not a cylinder.

I am seeing a lot of aftermarket cylinder piston kits for many other models in the $40 range, all with great reviews.

Anyone know where I can get a cylinder to fit this MS 271?

On one site it looked like the MS 261 and MS 271 used the same cylinder, is this true?

Cheer,
