Tasted the Simi, Sebastiani, and Hanna 2001s blind a few nights ago. It wasn't a very scientific or controlled experiment, but 4 people thought the Sebastiani was the best, 2 thought the Hanna was the best. I think they are all great for under $20. The Simi by far had the best aromas.
I can get the Simi for $17, the Hanna for $20, and the Sebastiani for $18 in Minnesota.
