I have one, the larger (60"?) version.
Keencut (UK) are great, even though you buy from a distributor & not direct from them, if you have a problem or need replacement parts you can go to them direct and they just want you to be happy.
My last machine was second-hand and the measuring scales, plus other bits were past it, they sent me new ones FOC - knowing it was second hand.
However, I HAVE had to use their excellent service too much - I think my new machine was made on a Friday at about 16:50!!
Has anyone used this machine AND Fletcher Terry's equivalent?
Apparently the FT can cut a 1mm (or something silly) sliver of glass, the Keencut cannot, in fact I don't think it could even score it.
I also own their oval 6 mattcutter and wish I'd bought the Fletcher Terry for not much more and I also wish I owned their (FT's) straight matcutter too, which is a far better machine then the Keencut Ultimat Gold - it's a good machine but the nylon bush bearings 'get to know' you and if you take on someone who is significantly shorter or taller, they rebel!
