I posted this over in the DIYChatroom as well, but here goes:
The home I am in the process of purchasing doesn't have a hood over the cooktop, instead it has one of those old fashioned fans that vents directly outside.
I am wondering if some make a hood that fits the standard size opening for such a fan so I could simply remove the old fan and put a hood in its place.
Any help?

The fans that vent outside are the best. Typically the old fashioned fans just circulate the air.

If it indeed does already vent outside this is a standard 4" or 5" pipe.

I like the fact that it vents outside, but the problem is that there is no hood at all which means that there is no light over the cooktop and more importantly the is wooden cabinets directly above the cooktop which to me is a safety hazard. I cannot get to the house to look at it until Sunday, but it is a basically a hole in the wall with about an 8 inch fans that blows air outside (on the inside their is a grate and on the outside there are flaps that fall down when the fan is off).
