Here is my two cents: I have a high regard for Myke Predko's book _Programming and Customizing the PIC Microcontroller_. His examples use the YAP (Yet Another Programmer?) board. I would use this programmer as then everything in the book is then cut-n-paste. After you finish the book, you will be a PIC guru and then we can ask you questions. You can download the files (GERBER, APTERATURE, Etc. -- filesize is about 15K) necessary to have a board made at any PCB house. They are at: http://www.myke.com/yap.zip I also think that Wirz is selling a kit and/or a bare board at: http://www.wirz.com Get the book and the programmer. You can't go wrong. NOTE: I have no connection with either Myke Predko or Wirz.
