I am their happy customer. I have successfully grown fluorescent yeast, and reproduced the CRISPR bacterial genetic modification protocol. Their support is awesome.

It is also possible to e.g. buy an old qPCR machine and corresponding perishables (I was slightly scared when a DHL truck delivered me a cold box full of dry ice), and run even more interesting experiments at home.

And, you can open an account at Sigma-Aldrich and order chemicals there as a hobbyist researcher (I did, and it worked).
