Remote Lock/Wipe on 3 Apps...and nothing else

[Sal]

I'd love the latest input from experienced users to compare these three apps:

Wave Secure, SMS Erase, and/or Norton Mobile Security (beta, in Market).

Which of these would be most effective, least buggy, and easiest to use to get the remote lock/wipe functions working on my unrooted Droid1?

(I already have a backup app I like.)

Thanks!
