Does anyone roast their own coffee beans?

I am tired of the coffee beans I get at the grocery store, they just don’t seem to have the flavor they once did. I think it’s because of the booming coffee industry in the past 15 years has grabbed the market of quality beans. Not only that, I think most beans tend to be over-roasted, or on the high roast side nullifying their true character. I know it’s a subjective thing, I just prefer medium roasted beans. So, is it a major hassle to roast your own beans, and can it be done inexpensively-sounds like it can from the proprietors. I think you can get a quality roaster for about $150.
What attracts me to this is, you can buy excellent green coffee beans super cheap, it’s the roasting part that’s got me wonder’n.
