Simple Web Search Utility

I search Craigslist postings on the internet in my area to buy equipment. For example I might search for “power amp?? The thing is there are a lot of different craigslist addresses in my area. For example: [login to view URL] [login to view URL] [login to view URL] So the problem is, I have to search for the same thing in the different areas by retyping each address and then typing in my search criteria. I only need to search one thing at a time. I need a program (I’m guessing like a web browser) that I can enter in the keywords I want to search for and have it check the different addresses I have specified at once, and return 1 list of links for me to click on to view the results. So I’m guessing I will need a place to enter in the addresses I usually search that are saved and able to edit when needed, ? and a web browser type interface for the gui. I also may want to select ? a category to search in also like Musical Instruments (which I believe is msg in their query string) etc. or “Computers?? which is “sys?? in the querystring. You can see their categories by typing in one of the addresses above. Notice the names are sometimes different in the query string that you are searching. For example, Musical instruments category is (<[login to view URL]>) I’m smart enough to put that in if I need to to make it easier. Pretty straight forward little utility program. I would like it commented well so I can make changes ti the code later if they change something on their end.
