My main reason for asking is that I found a vendor on eBay who is selling the Industrial Xuron micro sheer cutter (Blue Handle model 170-II) for a VERY good price. (starting @ $5) I believe this is the same unit that is sold by MM for close to $20.
My unit arrived a couple of days ago, and I'm very impressed, though I've not yet tried it on any PE.
I have NO relationship to this seller, other than being a happy customer. Just thought I'd pass along the tip.
