I spent most of last evening installing cable and ethernet lines in my house with my dad. We used the cool Motorola TalkAbouts I just got to communicate in different parts of the house. I got the two-way radios on ebay for really cheap. I guess the market was saturated...a lot of people were selling them. I got mine for 55% off the normal price. They're really cool radios too. They have a digital compass, barometer, and altimeter. Basically, they are top of the line for the 2-mile family radios. I planned to use them out in the field, but they came in real handy last night, trying to feed cable from upstairs to downstairs.
