If you want originals look at auctions.
You can get original art for the price of good framed print.
There are auctions in every town, lots of sub £500 stuff here for example

Viewing would normally be recommended as photos in an auction catalogue don't always show pictures at their best.
As for prints I have bought quite a few from here framed and unframed.
Depending where you live you can buy unframed which is easy to post in a tube then get them framed locally, Beware, if you are looking at large pieces framing can be expensive
