I'm getting ready to part with my prized MS440 with less than 10 tanks through it. I'm at a loss as to where to locate a strong enough box to ship it in without damage to the saw. Our local Stihl dealerships are pretty much geared to homeowners, so I seriously doubt that I could get a large enough box from one of them. I was hoping someone who ships a lot of saws could offer some advice on where to find a strong enough box that would hold the saw. Thanks in advance.
