on http://www.ps3trophies.org/index.php
there are forums for every game.
One of the stickies for each one is a poll on platinum difficulty level.
The easiest games appear to be
Sonic collection
Monsters vs Aliens
Prince of Persia
X-Blades
If you have some free time and are planning on buying a game anyway, you should buy Prince of Persia Used at Gamestop. Gamestop has a deal where you can return a used game for full credit within 7 days from purchase. So, then you can buy another used game from this list above, and repeat on and on, until you feel you want to actually keep a game. It's basically renting for free. I often have 2-3 games "rented out" at a time. Mostly DS games though.
