Probably any generic "cold shoe" will work fine.
The cheapest ones are all-metal so it's a good idea to cover the bottom of those with electrical tape.
If you want to put the flash on a stand, you might want to look into getting an umbrella, light stand, and umbrella bracket. You should be able to find a combo of those three for $50-60 or so.
B&H sells a kit with 2 stands, 2 swivel brackets, and 2 shoot-through brollies for $100. (If you happen to have a second flash unit.)
