I agree with zirrow. Even thumbnail size pictures of each model on the same page would allow the user to home in on the model or models that are of interest, instead of opening each menu item to see what it is. Having separate drop down menus for each model makes it very difficult to compare the models, and if you want to go back to an item that you liked, you must remember the model name, or start clicking all over again.

I personally prefer websites that make it very easy to find what I want without looking at everything to get an idea of what is available. If I don't find what I want quickly, I go elsewhere.
