I bought a cheap Harbor Freight illuminated magnifier to try grafting with this year.Didnt work out as it made it too difficult to judge the right size of larvae.But it works good for checking varroa on sticky boards. My favorite light source is a little 2 AAA cell Pelican flashlight.Used with reading glasses(didnt used to need them)I can see perfectly into the cell and the Chinese tool scoops em right up,royal jelly and all.I like the JZ BZ plastic cell cups,but still make a lot of my own from homemade dipping sticks.See,queen raising neednt be expensive.Just bail right in,you will have failures,but success too. ---Mike
