I'm thinking of picking up a new 4' level to use for both its intended purpose and as a straightedege for machine setup. The one I have is a really cheap one that I doubt is very trustworthy. Amazon has Stabila for about $90. I noticed that Menards has their Masterforce brand levels which Net Legend has are made by Stabila. Still kind of expensive at around $70 for as much as I think I'd use it for either use. Looks like the Orange BORG has some by Johnson in the $40 range that are supposedly accurate to 0.000-something-5 in/in and have a milled edge which I suppose makes them straight. What's good?
Local hardware store has an 8' Stabila they special ordered long ago that never got picked up that they'd sell for $50 but that's too long for me. He said he'd cut it in half for me.
