just upgrade to snow leopard, and speed download is working beautifully with SL, SD is just so easy to use, and powerful, it's the best download tool for Mac and the best ftp & iDisk client, it works beautifully with iTunes, since I always use safari and Firefox during my work, and I can say that SD is the best companion for both of these two browser.(for firefox just use the flashgot plugin)

Last but not least, I've got an excellent technical support from yazsoft, every time I send them email for technical help, I receive their replies within a few seconds(yes it's ture), so for 25$, you have good download tool, FTP and idisk client and a good customer service and more, it's worth every penny.

just bought this app ten days ago, so far so good, but adding a little cocktail to it will be appreciated, like showing temperature or weather information, I think I'm not alone for this opinion, so waiting for another upgrade, and look forward to some new features from the dev..
btw, it's a good app and it worths the money. :D
