I could be lazy and not answer, to match the mount of effort you wanted to put in. Don't forget, we do this out of our spare time, not because we have to.
Yes, the 10D has mirror lockup. I believe the D100 does as well, long with the Canon 1D, 1Ds, & Nikon D1, d1x, d1h, d2h (I believe). I didn't see it in the Fuji S2 Pro, but I thought it had it.
The Digital Rebel doesn't have mirror lock up.
