Ah I think I know the tool you speak of

I've done a lot of home repairs and DIY stuff before so I don't doubt I can do it. If I can get all materials for around 3k then that would be nice and would be easily doable. Have to see. They said that was their most expensive stuff so I figure there is probably some stuff thats a bit cheaper. Might be a good time to put in some upgraded insulation as well as it is a rather old house. I still have to look at the inside before I make any sort of decision, and there are a couple other houses I need to look at.
