Product review (5 stars): It worked
This kit worked great for me.  I converted a new frigidaire gallery brand gas oven to propane.  Instructions were sufficient.  I am not an expert by any means but am rather handy when it comes to learning or figuring it out on my own.  I had no problems and completed this in about an hour.  I could do a second one in half the time now that I've learned from this first conversion.  Good luck.  I would recommend calling a professional if you are at all concerned about messing it up.  Don't risk your safety to save a couple hundred bucks.  That said, don't be afraid to try to learn something new.  Just take your time and follow the step by step instructions.
