Ha, ha ...sprung! I was talking about Leon too, I conscripted him the other day to modify a couple of my supers (that used to be his) to make some swarm traps. We have the same last name coincidentally. Leon just buscuit joined a heap of his kitty litter feeders into ideals ..he should have sold some of them to you! You'll have to wait for Shiploads to open to get a cheap supply of suitable plastic trays though. They work well with the floats to minimise drowings. The flyscreen across the top would be a good addition too and then you wouldn't get a face full of bees every time you topped them up. I'm going to try out the Fat Beeman's "No Drown" Feeder (Miller Feeder variation) with a screened ramp - a bit more work than Leon's design and probably no better, but doesn't require a kitty litter tray.
I live in Saunders Street near where the yellow one tonner is, but I'm looking for a bit more space. Desperately need a bigger shed. We went for a drive down your road recently looking to see what's for sale, but I can't remember seeing any hives.
Looks like we should start a new topic like "Wynyard, the beekeeping centre of the world" as I'm getting off topic with all this excitement.
