Much as I like to slag off BD it has to said that their 4 colour option
works pretty well. Our fourth colour option was installed a couple of weeks
ago and I've used it a lot with no problems. I haven't used or even seen a
Coulter XL so I can't comment on them. Don't believe the reps, if I were
you I would want to see both instruments in action ideally with your own
samples.
