The biggest question is the condition of the batteries. Replacement forklift batteries, particularly 36v, are expensive. Also, 3-phase power might be required to operate the battery charger. Finally, there are the shipping costs from PA to Washington. Assuming a working charger is included, I wouldn't pay more than a few hundred bucks for this particular one, plus shipping. It really depends on your specific needs.
I have several 12-volt walk-behind pallet stackers in my home shop. They are cheap to buy, easy to fix, and are small enough to navigate into tight areas, which fits my needs perfectly. If I wanted a larger forklift I'd look for an older diesel or LP model, but not a battery powered one.
