I know. And I'd be happy to pay for a license when this whole thing compiles
and runs the way we want.

You should check the license... most time limited compilers are for
evaluation and not for commercial use. You normally can not ship a
product with an eval compiler. That said I don't know of any compiler
company that has actually enforced that clause.

Thanks for all comments and opinions. I have decided to go for the MicroChip
C18 compiler. It gives me 60 days time to port and finish the current code
and so far, things are looking good.

Take a look at CC8E from B Knudsen Data. I've used for years and found
it to be excellent.There's a free version for evaluation.

I have used the free Microchip compiler for several projects. So
far I have not come across any major warts except that out of the
box the libraries are compiled for large memory support (24 bit
pointers). First thing I did was recompile for small memory.
You have to remember it is a Harvard architecture and constants
stored in flash cannot be accessed as normal memory. The
compiler will take care of part of this. For the memcpy,
strcpy type library routines you have to remember what memory
the source and destination reside in, and use the proper
library routines.

I use the Microchip C18 compiler for PIC18 and have had relatively few
problems.

What do you mean by "very good"? The last time I evaluated IAR for
the PIC18, it generated code that was 50% larger than Hi-Tech (~36K vs
~24K). It was so large that I wasn't able to see if the code actually
worked, because it was too large for the 32K target processor.

I did not know Hi-tech when Bust.
They actual where better before Microchip bought them. Faster updates
and bug fixes. It is not a cheap compiler, but it has a free and eval
version. I use the older ones with no problems. I am using the New Lite
version as a test on a new program. So far so good.
