I modified a GE C1033 for IR photography today (Picked it up from a bargain bin at a large retail chain for $70odd this morning) It doesn't affect the (rather poor) aesthetic at all.
All up it probably took me a grand total of 15 minutes from start to finish but only had exposed film negative to use for the IR filter so isn't ideal. Might get my hands on some Lee gel filters to trim up and see if the results vary.

The guide i very loosely followed
I'll keep playing with it and with Lightroom settings for the development of the images and see what i can come up with. So far i'm not hugely pleased with the results of any image in anything less than great lighting but we'll see how i go, might even try and sync up a bigger flash to help that out. It's a pity the camera doesn't shoot RAW but maybe i'll find a nice Canon G9-10 i can pull apart.
