I bought a 359 etech today for $200 without a bar. I bought a 20 inch bar for the 455 rancher, because that's what the guy told me the saw was. It doesnt fit so I'm looking at bar and chain recommendations for the 359. What thickness chain runs well on these, .050 or .058. It looks like I can get the .058 bar a little cheaper. I've been looking into the saw, and might be porting it to get a few more umphs out of it. I'm not a pro, will probably run the saw few - several times a month.
