I got mine off Amazon, by Porseme. It's holds 280ml which is on the bigger end so it runs longer, but it has a timer on it also. They have glass and ceramic, I got the a couple of glass ones and painted them to match the rooms I put them in.
I use oils I found on eBay, not sure if they have another site, but if you search "essential oils chanel" (one of their scents) and sort for lowest price it is in a green jar with Mayci on it. Hope this helps
