We don't have one in house either, and have instead out-sourced to a
couple of sequencing centres in the UK with 454 machines.

I would say Roche's own tools are the best reference, but these only
output FASTA and QUAL, not FASTQ files (at the moment at least). So
yes, being able to compare a Biopython SFF to FASTQ conversion with
that by Flower (or anything else) would be handy.
