original site, new domain or sub-domain

which one is best for affiliate pages?

I have nearly completed a few affiliate pages related to a few products on my site.
Problem is I'm at two minds which route to take.

Should I:
1) Add the pages to original site
2) use a new domain & add link from original site to affiliate pages
3) use a sub domain & add link from original site to affiliate pages

I'm thinking 2 or 3.
any ideas?

1 would be my choice, with 2 running a close 2nd. I'd never do #3...

GREAT! thanks a lot Brett.

Why never #3?

I think that #3 is the best way
imho

3 takes away from the original sites PR - out bound links pass PR.
By going with 1 you have people linking to your site and getting the added bonus of link popularity along with a sales force.
