Investing in a scale to monitor your weight doesn't have to break the bank -- you can find yourself a good, basic model for as little as $19.99. Want more bells and whistles? Up goes the price, which might be worth it if the thing helps you score diet and fitness success.

It hasn't arrived on the scene just yet, but soon to be unveiled is a new pricey gadget called eScale, which is a bathroom scale connected to the Internet. BodyTrace, the company behind the technology, thinks the instant feedback you'll get from using this product will make it well worth its $119 price tag. You decide, here's how it works:

Just step on the scale to weigh yourself, and your weight and BMI will be wirelessly and instantly transmitted to a website where you can follow your progress -- you'll have a page that looks something like this. You'll also get access to recipes and diet/fitness ideas, and you can play around with an interactive food diary, Twitter about your accomplishments (or setbacks) and check in with the BodyTrace blog -- posts are dry and technical right now (evolution of the design and styrofoam packaging for the batteries), but maybe they'll liven up once the product starts delivering in September. You can pre-order here.

What do you think: Is the eScale worth its price? And will you buy it?
