I don't have one yet, but if my cuttings strike then I'll let you know
They're great plants, they just don't work like your normal Drosera
I can understand wanting to buy from a hobbyist or someone enthusiastic about them. I've noticed the difference in the health of the leaves in the time that I've owned it. I'm sure they didn't do a "bad" job, but they didn't grow it the same way. Regia needs a LOT of food, people feed them like capensis and their seedlings die off.
If you do end up going the commercial route, definitely keep that one in mind. Wouldn't want you having a bad time before you get the chance to enjoy it. I use about 7 osmocote smart release pellets in a 6x6in pot (3-4 for 2.5in) and feed it moths or whatever it catches and the plant is doing great. doubled the size since I've owned it and the leaves are more "robust." It doesn't look weak anymore
Today I will do what others won't so tomorrow I can do what other's can't.
