If you weren't meaning the 'Sunburst' cultivar specifically, I have a Satsuma.
I chose Miho for a few different reasons. It is suited to a container and more cold hardy than other cultivars.
I found mine in a local ACE garden center around this time of year in 2008. It was supplied by a south Texas grower.
You don't need two trees to produce fruit.
I have found the Satsuma to be problem free. I had a lime tree that had constant issues with mealies but they never bothered the Satsuma even when sitting right next to it.

and due to needing more coffee this a.m.
It is not uncommon to see blooms (which smell wonderful) and fruit of the little tree at the same time. I do overwinter mine in the greenhouse as I wouldn't want to forget it and loose it to a freeze.
