No experience whatsoever but I took the time to look over the tomato varieties and speaking just for myself I wouldn't order from her.
There are pictures that have been scanned from other sites that I recognized, one being from the public SSE catalog. That is illegal.
Looking at some pictures I know what they are but she's renamed them and I have absolutely nothing to do with someone who does that just to make something look unique/special.
$3 for 20 seeds for who knows what you're getting when there are so many wonderful seed sites with known varieties and lower prices raises yet another issue for me.
