I have three weather radios:

Midland 74-250 - This is the yellow portible one. I don't really like it as much as the other since I really stumble through use of the controls each time I use it. Its just not as intuitive as the Oregon Scientifics. One of the big flaws is that it only runs on batteries. Plugging in the AC adaptor is only for charging the cadmium batteries.

Oregon Scientific WR103, which has been replaced with the very similar looking WR601 - This is the silver portible one. I really like this radio. The controls are fairly intuitive and easy to use. This one will run off of AC via the charger.

I'll recommend the WR601 to you. It works well both portible (I take it camping with me) and on a desk.

I also have several of an Oregon Scientific desktop model that can pretty easily be used portable. I think it is no longer available - probably replaced by the multipurpose WR601.

I tended to buy my weather radios from http://www.ambientweather.com/radiosnoaa.html if that helps.
