I have had very good results with the MELabs PicBasic Pro Compiler. When I called them to purchase it, I told them that I have a Parallax programmer and asked if it would work or if I needed to purchase their programmer. The guy that I spoke with was very honest and told me that I didn't need to spend the money to buy their programmer. I have been using the PicBasic Pro software with the Parallax programmer and I think it is great. Maybe I'm not using some of the functionality that others are. I'll admit that I am not a heavyweight programmer but, for my application, It has worked very well and I recommend it. Max Toole, Electronic Innovations,Inc.
