Shopping search engines are great when you already know what you want. But what if you want to buy a digital camera for someone for the holidays and don't have a clue where to start? Wouldn't it be nice if you could pick through the zillions of options by process of elimination?

Popgadget has partnered with Techselector to bring you interactive buying guides that take you through a series of questions to hone in on the product you're looking for. For instance, if you select the digital camera category, the first selection you make relates simpy to size: mini, compact or full size. And then you get the following sequence of questions with multiple choice answers: what you're going to use it for, whether you want a viewfinder or LCD display, the size of the LCD display, the level of zoom you want, what kind of storage you'd like, how you want it to connect to your computer (USB, firewire, etc). In the end, you get a list of cameras that fit your requirements. And if you don't choose to buy one of the products in your search results, you at least have a more solid starting point for doing further research.

We know that Popgadget readers aren't all tech geeks (or at least not in every area of tech), so this is for those of you who want a friendlier approach to finding just the right product for your needs. Give it a try (or let someone less tech-savvy then yourself give it a try), and let us know what you think.
