For a cheap/free portable, the Kenwood TK-2180 is an excellent VHF choice. It's the portable version of the TK-7180, and if you have both, you only need to maintain a single profile, just editing the button functions to program the other unit. For your spreadsheet, no mods needed for full VHF coverage.
The advantage of the 2180/7180 over the TM-281 is that you have more memories (128 alphanumeric memories) more alphanumeric characters in the display, and separate banks.
I use my 7180's and a 2180 for VHF scanning. I have a TM-271A (predecessor of 281A) that I keep around because it's frequency-agile, but I don't use it for scanning because I'd have to scan all 100 mixed-service channels at a time.
Btw, you cannot "name" the banks with the 2180/7180, so what I did was enter a dummy record as the first channel of each bank with the contents of that bank. So for instance ch-1 might be named "SAR" with a random freq like 150.0000, and I've unchecked the scan-add box. So as long as the radio is on the first ch of the bank, I can see the bank names as I step through the banks (if it isn't already obvious from the alpha tag).
I can usually tell what's in the bank from the ch list, but I figured out this method when I gave a 2180 to a buddy who was just getting into scanning, and he didn't necessarily know the channels. My radios are now set-up the same so I still only have to maintain 1 profile, just changing the power-on message to his name.
Be wary about purchasing from online auctions. Go to a Kenwood LMR shop and see what they have for trade-ins, that they can check or have checked on a service monitor. There's a lot of the analog radios floating around as companies migrate to digital.
