The manufacturing sector has been hit hard. I agree with smiled that it might take a while to find employment. Salem is the cheapest of the metro towns.
Corvallis has Corvis, ATS, and HP (which is downsizing and laying off ).
Not sure what is in the manufacturing sector in Eugene. Anyway...Salem would be your best bet for affordability, but that is not a huge sector here.
If you go to
www.statesmanjournal.com, that is the local newspaper and you can see what is out here locally.
www.Oregonlive.com is the Oregonian's website.
There are many smaller towns surrounding our larger metros, which offer more affordability.
