Yes, I have Move. I bought it mainly for Light Gun type games. House of the Dead: Overkill, The Shoot, and Time Crisis: Razing Storm. It works well for those kind of games. I don't use the Sharp Shooter, though. I use the Shooting Attachment. I got it for $7.99 at GameStop.

Also, House of the Dead 3 and 4 are coming to PSN. I love those kind of games, so Move was worth the $58 I paid.

I don't know how well it works for the two games you mentioned. I bought the Director's Cut of Heavy Rain for $14.99 on Black Friday, but I haven't played it yet.
