Sinner, thanks for the response. It's starting to make sense now. :-D

I've been searching around the Net trying to get some answers regarding technic sets (since I've never purchased one), but I'm a bit confused. Can someone answer the following questions for me. 1) I understand how the power functions and engines work, but the sets without power functions... are they just models? For instance, I've read reviews where people complain about stiff suspension on a car, but if you're just rolling it around by hand, does it even need suspension? 2) The gear box. This one I just don't understand. What do you do with a 5 speed gear box, when there's no power functions in the set? 3) Some sets have power functions, but no remote. Does that mean you turn it on and it moves until it hits a wall? At which time you pick it up and face it in another direction? I think I'm missing something and sadly, from what I can tell, the lego site doesn't really explain a lot. Some of the technic sets look quite impressive and I'd be interested in purchasing them, but I'd just like to know more. Also, I've read reviews that have talked about chasis, 4 wheel steering and 4 wheel drive, which are cool, but the set didn't come with power functions... so again, how do you use the steering and the 4 wheel drive? *wacko*
