He (Dave, HobbyCNC) recommends a couple and gives links on his site but some of us made ours out of old microwave transformers. The rewinding is not too difficult if you're not a stickler for appearances. Bubba tells how here:

The Hammond 30vac xmfr Dave recommends will give you about the max voltage the board can handle (30 vac x about 1.4 for going thru the ac/dc conversion = 42-44 vdc. The board handles 44 vdc max).
