I thought the TR12 was the model which preceded the M12 (mk1). I can recall references to them in Fine WoodWorking magazine 25 or more years back (I just looked at a few old copies of FWW and they are certainly advertised in FWW #37, Nov/Dec 1982, yes eighty-two!). I recall reading that theye were pretty reliable routers with one minor flaw - Hitachi didn't put fully shielded bearings in them which made them prone to premature lower bearing failure when used constantly in a router table. I also recall the solution; the bearings are apparently proprietory so 3rd party shielded replacements should be a breeze to obtain when the time comes.
Hope that helps
Incidentally, that Amazon page seems a bit screwed up..... "Here is the ultimate value in 18V cordless combo kits" ?????
