Memory Wire - A Recommendation?

Memory Wire - which do you use for bracelets? My mom loves memory wire bracelets, and I wanted to make her a couple.

I have used Bead-a-lon, and I am not a fan of it. It pulls out of shape way too easily, and cannot hold much weight.

I bought a generic brand at Wal-Mart several years ago - just on a whim, it was cheap and I thought why not. I loved it, and I haven't been able to find it since.

What would you recommend?
