Alastair, you've nailed it on the funding point. Often it comes down to money.
I also hadn't thought of the test strips (the Agdia ones for Orchids are hard to get here and only test for two of the three main viruses, so sending samples to the lab is the better option for me). I'll have to see if there's strips available for Irises and how the cost compares to lab testing.
As for retirement, that is a long way off for me, but I, too, cannot see myself running out of things to do!
