Penzey's has Sichuan peppercorns

I'm with healthierkitchen on this, it does include Sichuan peppercorns, which of course can be as hard to find as Five Spice itself.

My boring supermarket stocks funny little tied bags of ground spices for pho broth in in their "ethnic" aisle. Comes in a little box not too far from the coconut milk. I think that might work for you.

I think it's got ground Sichuan peppercorns rather than ginger. Also available at some Asian markets and spice shops!

I too have found allspice to be okay in a pinch. But be aware there are other five spice powders out there. Tunisian Five spice powder is also a great, if not exotic option.

aargersi is right but you might want to use star anise which is a little bit different from anise. Star anise is easily found at asian groceries.

it has cinnamon, anise, clove, ginger and fennel .... you could make your own or use a subset of those spices to your taste. You might also consider allspice and/or mace
