A problem with serial LCD that I have had, is they require to many programming delays and may interfer with interrupts. On the other hand a Parallel LCD is very fast, but requires too many I/O pins.

If you are using it just temporarily, perhaps a self contained data acquisition - LCD would do the trick. A cheap Parallax SX chip (aprox $3.50 + $14.00 for a 4 line LCD (ebay) ) and use the SX/Basic example in the SX-IDE. That way you don't have to add any unnecessary code that may interfere with your actual program.
