Hi,Commercial but non-biased response (we do not sell scanners just arrayers)
We have two scanners from Applied Precision, one about a year old and a brand new one. We also have access to two GSI instruments. Whilst both types have there positive and negative aspects, we have had better service and support from API.
The software does take a bit of getting used to, but once you are they are very reliable, quick, sensitive etc and as such out of the two the API is what I would recommend.
We have recently looked at the Alpha Innotech instrument which looks very good as well.
The flexibility offered by these scanners over the laser scanners for changing filters etc (at significantly lower cost) was a big positive. We have also found them to be just as good at low signal regardless of what the company line from the laser scanner suppliers!
We do still use the GSI instruments on occasion.
