You are correct once the internal filter is removed and the infrared filter installed you cannot use the camera for normal work. That being said, if in the future you decide that you no longer want the camera to be infrared you just need to have the infrared filter removed and re-install the original low/pass filter and your camera is back to standard shooting.
A couple of suggestions: 1) If your not using the D40 that much, consider getting that one converted to infrared. There is a world of difference between using the filter and using a converted camera.
2)or if your just not sure yet, you might find some decent prices for used filters on Ebay or at local flea markets or camera swaps. I bought my first Cokin Infrared filter at a camera swap for about 10 bucks. As a matter of fact if I can find it I'll sell it to you for 10 bucks.
