DevTeach (www.devteach.com) is one of the best deals in .NET conferences...it's a great small conference that gives you access to many of the regular .NET speakers but in a much smaller venue. Personally, I'm giving a pre-con called "WPF Meets the iPhone" which elaborates on my article in CoDe Magazine (http://www.devx.com/codemag/Article/37589). In this pre-con you learn a lot about WPF in general as we do something fun--recreate the iPhone user interface in WPF.
