Be aware of the cost though. If you use low voltage programming you lose the
I/O pin that selects the programming mode. Even worse this pin is PORT B, pin
3 on the 16F87X parts, which means that it's in the middle of a perfectly
usable 8 bit port.

I try. The only conceivable downsides that anyone can attempt to argue are
availablilty of the new parts and the fact that you can't drop in code for
a 16F845 directly into a 16F628 without a coupl of very minor modifications.

It's on my laundry list of things to do. However I want to PCB it right, so
I haven't yet tackled the project.

No problem. Glad that the TLVP could be useful to you.
