The Radio Shack Pro-97 or Uniden BC246T would both be good choices for the uses you've stated. Both are around $220, but the Pro-97 goes on sale for (I think) $180 every few months.
If you're looking for cheap, a used Radio Shack Pro-95 can be had for around $100 (or even less). I have one of these, and it's a great scanner with good loud audio and alpha tags.
