Transformers - help me please

[tostaky]

which one transform on its own? (with presumably a remote control? or at a push of a button?)
I asked for simple one for DS2 and my parents told me they bought one that transform itself... i want to look it up online because 1) i am sure it is very expensive and i dont want my parents to shed so much money on a toy and 2) i am pretty sure all the fun is in transforming it yourself...
Just want to be sure before i - once more - upset my parents... (roll on xmas...). Hopefully they would have hold onto the receipt...

We bought ds the flip and twist grimlock as a starting school present. You basically pull the tail apart and spin it. It took him a while to get the hang of it, but he enjoys it. It cost about £23.

There is also a huge grimlock for about £70, but I'm not sure what that one does.

My son has a "Twist and Lock" Grimlock which is easy to transform.
Other easy ones are "One Step Magic" and Playskool ones.
