I'm not a big fan of aluminum crampons where you're likely to encounter mixed conditions - i.e., snow, ice and rock. They don't hold up well on rock.
On the REI link Steve Peacock listed, the Black Diamond Contact Strap is a good all around crampon that will also work on Rainer. For a bit less aggresive crampon, look at the same Stubai model you listed, only in steel. It's about $5 more, plus a few more ounces -
