OP

Quoted from Nokoro:

Ah, thanks. I should have mentioned that I don't intend to move a pin by myself. I would always have one or two buddies to help. I still want a decent but not expensive hand truck to smooth the process of getting it up and down the stairs. I've tried the carrying method, and it is not fun.
Do people have an opinion as to whether it is better to get one with big wheels or one with a stair belt? It sounds like the stair belts on the cheaper models don't last, so perhaps I'm better off getting one with big wheels . . . .
