Devastator Squad in Rhino - worth it?

I've been contemplating this for a few days... would it be worth parking a Devastator squad in a Rhino for protection?

Pros:

• Rhino's armor of 11 makes them impervious to bolter fire.
• Possibility of 12" emergency move if needed
• Repair possible if Rhino immobilized
  
• Vehicle and squad can target independently
• Not significantly expensive (cheaper than extra marine + heavy bolter)
• Potential for two Storm Bolters
• Likely that entire squad would survive vehicle exploding

Cons:

• Only two models can shoot from fire points
• Points could be spent on additional long range weapons
• High strength fire magnet

So for a mere 175 points you get 5 Devastators with 2 missile launchers in a Rhino armed with two Storm Bolters and a Hunter Killer missile. For that same cost you could get a 5 Devastator squad with 2 Lascannons and a missile launcher.

Have you done this? How did it work for you?
