What you should be able to access in terms of great art is something that might be reliant on commercial distribution. However many collectors find ways of getting to their preferred artists and collecting their work. There is a system at work for this more rarefied process but when you need things quickly, commercial items may do.
There are many variations as to how you could get great works, and not only for the price consideration. Many people have excellent impressionism prints, a style and movement that actually had its heyday over a century ago in France. While this has been imported and incorporated and even has modern day practitioners, the most recognized artists here are from that era.
Impressionism is distinguished by the play of light on the canvass, and it is one of the most beautiful of styles. From it grew pixilation and dot matrix printing processes, although these have a far disconnect with the original painting process. Most Impressionist share a passion for color though and may dot their work with pure spots of dyes and tones.
While complex, the original paintings can be copied in print very well. Today, the definitions and color separation have definitely improved such that you could have certain effects added to the original, like better definition. However, you might want to have your print as close to the original as possible and this is possible today.
In fact prints like these can be picture perfect, usually with regards to the materials used. You might not even be able to know which is a copy and which is original when you put a framed print and the painting side by side. Copyists, or those painters who reproduce works through painting cannot do it as fast or with exacting precision.
Printing has from the start provided art with a means to be more accessible. And this style was in fact another form of art that was independent of painting for many years. When folks found out that photography can be reproduced it was not long before this was applied on the copies for commercial distribution.
Of course prints started out primitive, or rather less than perfect. However technology was quick to catch up and provide more and better stuff. Eventually the trade became recognized for being able to make all sorts of copies for consumers on a very large scale, which was something museums and artists appreciated.
In fact some artists turned towards printing in large amounts of copy from their original works. There might be other kinds of stuff that are doable, but this is one that can be done anytime and with far superior prospects than most. It is like photocopying or better, and that is a thing that has made even the youngest folk know their art.
When you are in search for great alternatives to display on your walls there may be nothing better than Impressionist copies provided by ateliers or studios. These are often run by artists and thus will have at minimum assured quality. This alternative is something available to anyone.
