Well Linda I would advise using the recommended parts for your laptop.
I really tried hard to locate a good web site for you for parts, but then I realized a price I'd find fair might be too much for your budget.
I did a Google search and came up with over 227,540 Hits (amazing!) for the key words laptop parts
I would suggest you try your own search engine and check out the various web sites available and do price comparisons, then decide what's best for you.
