I have the Emco?? mechanical/manual one and its been good. Was around $150. Honestly haven't figured out why they say not use an impact gun on it, unless they figure guys will overload it. I have no issues when done with some common sense. Gotta keep them threads lubed up on any of that style.
As for the rest, have everything from the diaphragm pumps down to the Coats tire machine and large tire spreader which is the cats ass for boots or plugs in tires. My fav tire irons are the ones that come with my old Russian tractor lol, though must have a dozen other ones including those special ones for the lock rings on the old multi piece wheels. Been eyeing up that gizmo known as the Blue Cobra from Ken Tool, that thing is slick for tubeless truck tires. Seen some different offshore brands of it, not sure the quality is there though.
IMO, fixing tires is not for everyone. Requires patience and a strong back lol. And lots of inventory of tubes, patches, valve stems and more, and even then a guy don't always have what you need. Tubes just don't last anymore, have had so many rot and crack sitting on the shelf in the dark. Tractor tire tubes, I won't put anything in but Firestone. You get what you pay for. Those chinese tubes are f'n garbage IMO.
FYI I get all my tire repair supplies from B-Line out of St Albert. If I time it right, the salesman's truck will stop by and drop off my order when in the area about every three weeks as he is making his rounds of the area shops. Otherwise I just pick it up in person. Great guys and prices and well supplied!
