I've priced both...Toyota and Hyster cost pretty close to the same amount. Depending on where you are in the US, Hyster is more pricey. Toyota does have a great lease program though.
I haven't had any problems with my new Hysters, and I have over 100 of them total, both cushion and pneumatic. The wet disc brake option on the 8,000lb pneumatic Hysters is warrantied for 10k hours! My Hyster dealer did a parts pricing comparison and it was well over 20% difference. The Toyota salesman didn't know what to say. Maybe the Toyota truck is better, but the Toyota salesman got out hustled (or maybe I did!)
So far no problems and its been about a year...cross my fingers! I'll probably show up tomorrow with 5-10 machines down. But like I said before, the Hyster dealer support is great. My care reps at the various locations show up at least once a week to make sure everything is going okay and do surveys on tires, forks, etc. I guess Hyster just gives me peace of mind.
