Two great tools that I have been lately messing with. I love the fact that how much these can make you productive by creating the Bussiness Object so quickly. Heck for myGeneration template I went even further to customize it so that it now even prints out HTML/ASPX tags for me depending on database column that I could further customize to suit the business needs.
Very tight stuff, worth checking out if you haven't already done so.
You can download .NETTiers templates for CodeSmith and even build out entire application.
