I have these ones:
FieryRed Recovery Traction Mats - 2 Pcs Recovery Tracks Traction Mat for 4X4 Mud, Sand, Snow Traction Ladder Red Tire Traction Tool : Amazon.ca: Automotive
www.amazon.ca
They are good for at least 3 recoveries so far in deep snow, one at -10 or so, one a bit colder, and one at -2 or 3 (Celcius). For $70 CDN, if you only plan to use them a couple of times I think it's hard to go wrong. I purchased them for a similar reason as you -- I had a trip coming up that I wanted to be prepared for, but didn't have the spare cash for a full set of MaxTrax at that time, and I didn't have the time to mount up my winch, so these were a cheap backup plan for peace of mind. In my research, these are re-branded by several sellers, but as long as the traction boards themselves look the same as each other, they likely came from the same manufacturer regardless of branding (And I mean the exact same -- the trad patterns, shape, etc. all match).
BUT -- these are NOT Maxtrax. The plastic colour has broken down after about a year in the sun mounted on my vehicle (faded) -- I do not know if that has impacted function as I've not tried them since noticing the fading. Still, if my trip was going to take me through places with cell coverage where, if I was really stuck, I could call for help (i.e. a tow truck), I wouldn't hesitate to take these with me as a first line of recovery. As others have said, don't spin your tires and they'll get you out of most snow encounters. I wouldn't want to depend on them with my life, which can be a reality for winter touring, but use caution on your route and you should be fine.
