Greg: I just love your plant, it's so beautiful, reminds me of the (related) Chirita plants I once grew. I grow a couple of miniature Sinningia's but they aren't doing real right now. I keep thinking I might try one of the standard Sinningia's and I love the color of the bloom on yours but everything I find for S. insularis shows coral/red colored flowers. Your beauty sure doesn't have the same color flowers as those below which are listed as S. insularis:

But, upon further searching I found this one, Sinningia 'Purple Crest' x self:

When I grew Chirita's I was drawn to the lavender/purple shades ... and I love the purple Sinningia's.
