Is Hip-Hop still worth buying?

While listening to a local Hip-Hop radio station an eerie thought flashed across my mind. Is Hip-Hop still worth purchasing? Who still buys Hip-Hop music from the ORIGINAL artist? With all the MixTapes and MixTape DVD's being released by lesser known but locally acclaimed DJ talent, who needs to buy a full-length album? The last album I bought was nearly 2 years ago. I think it was a Nas or J-Live album. Everything since then has been either downloaded or copied. So this brings me back to my first question, Is Hip-Hop still worth buying?
