you will be happy w/their speed of mailing. I ordered and they gave me an expected delivery date. It was a sunday so i never expected it. I got home that day and got a notice of attempt to deliver.
Also, when you go to take the original DI out just be careful about the red clip you have to undo BEFORE trying to disconnect the plug/connector. I was worried it would be a problem so i took my very slow time and was done in only a few minutes once it was disconnected. paul.
