Howdy Greg, my actual 350D was bought new and modded from Hutech with the clear AR coated glass option, my IR pass filter I got off Ebay, some links here

Mines a 58mm which suites my Canon kit lens, I bought separately a stepdown ring from a local photo store so I can fit it to my 50mm f1.8 lens. Yes I can shoot IR hand held in daylight with fast enough shutter speeds. Mind you a 40D would be better with its live view. With my 350D I have to take pics then check focus by trial and error.
Normally a 58mm filter is too big for a 2 inch focuser but it will fit in behind mine so I can use it in my telescope.
My filter is 850 nm cutoff
First shots here
