Shaggs: I got this one on ebay.com(US, not local au) from a seller with lots of good feedback, the saw is as new, ran for a few minutes.
If ya sift through and keep an eye out there is a few on there like this.
A lot of sellers wont ship outside US though
I wouldnt bother on anything with a bit of hard use under its belt though.
Cost $589USD + $110USD shipping + $8USD insurance = under $800AUD
I think retail here is about $1300-$1400.
Oh came with a hardcase too
Therrin: Depends on what size saws you've already got. If i didnt already have something bigger i'd get a MS440/460/441 over the 361.
