A year or so ago, the CCS compiler was a bit buggy; by now its support for
one and two-byte unsigned integers and all the normal maths with them is
stable; it has support for signed and floating-point maths too now, but I've
not used those features yet.

As for Hitech, it looks like a good compiler.  It does cost more than PCM,
but it supports additional features such as "long"s that are 32-bits (I
wish CCS did, but it doesn't), etc.  On the other hand, its library of built-
in I/O is from what I've heard a bit limitted (on the CCS compiler, if you
tell it what pins and baud-rate you want for a bit-bang port, you can use
"printf"s just be writing them).

Anyway, I don't know your exact budget, but I know I've gotten a lot of use
from the CCS compiler; Hitech looks like it may be a better product, but I
don't know whether it would be worth the extra cost.
