If you came on and said "I got a Logan mat cutter on eBay!" then we'd have a bigger contrast of equipment quality to respond to!
OK, I'm a dork, I mainly use a Logan 60" matte cutter bought on ebay.
I bought it because I thought I would need "just a few" 40 x 60 mattes, nobody around here could (or wanted) to cut them for me. Never thought that would be my bread & butter size, which it now is. My old Fletcher could only handle a little over 40.
Yes, it's, um...somewhat poorly made in many respects. OTOH, the rail system is very rigid, always makes perfectly straight cuts, and the double-sided $0.15 blades stay stunningly sharp for exactly one large matte, after which I put them in the slotted peanut butter jar. No wondering about blade condition, just use 'em and chuck 'em. I dare anybody to find my teensy little overcuts, the cut is that fine.
I have the very upscale version with the cutter head rigidly held by the rail, not the "hold it in the slot" version.
Yeah, the only reliable gauge is the matte width one which can be quite accurately calibrated if you know how. Yeah, it's best to make marks on the back of the matte rather than just setting the stops. But it does have an easily adjusted end stop which is all I really require beyond just a nice straight cut.
And it cuts 8 ply just great, all you have to do is screw in the fiddly little 4-40 hardware screw to position the blade right. It's so down-to-earth!
Long story short, I no longer use the old Fletcher 2000! Maybe if I was doing production mattes, I would.
I know I'm not the only one, come out of the closet you guys and feel the sunlight!
