Best SKATE for singleplayer?

Hey I want to get one of the SKATE games solely for singleplayer. Which one do you recommend keeping gameplay and the price of them in mind?

Buy both Skate 2 and 3 if you can but personally go for Skate 3 it has alot more cool features, graphics are nice, lots more to do.
