I was temporarily providing the PHNL feed with a PRO-95 which I think was one step up from the PRO-94. The only difference I think is that the PRO-95 had more dual trunking channels, 1000. I think they have a PRO-96 with digital trunking that is even better than the PRO-95.
You don't need to depend on a supply of batteries with the PRO-94. You can get a simple A/C adapter plug for the wall. It says 9V on the side but you can make do with something around 6-9V. On my PRO-95 I got away with using an old AC adapter that had the same plug that put out 6V max. It worked. Plus if you wanted to go portable away from the house, a handheld is much more convienent. Get a cheap set of NIMH rechargables if you go portable, it will save you a lot of money.
Radioshack models are pretty good and last I remember they were on sale for a decent price. Plus if you get bored of airband unlike some other scanners such as Sportys you can always have fun with trunked civil and private use UHF channels and all the other radio bands bands. Feed is now on a Uniden Bearcat base, BC785D.
