As of 8/1/2010: Silent Technology is not accepting new orders. We will continue product support for our current customers, but we will not be shipping new orders to either individuals or bookstores. We apologize for any inconvenience. There is an online version that you can use if you wish - find it here. Some stores may still have some inventory, and you can also check eBay or craigslist for used ones. Good luck on your test!
