The variety of Michael characters is nowhere near the variety of Victoria characters, and I honestly haven't found too many unique faces from the morphs available. I have found one morph pack in the Marketplace worthwhile, which is Tammy's Mike Morph Pack (five faces that are genuinely unique for $5.95).

As for textures, this site has the most free textures for Michael that I have seen, if you can't find what you want in free textures here, you might have to end up selecting something from the Marketplace to buy.
