Is it worth it to pick up a mono cartridge?

I own a technics 1210 with a Denon 110. Would it be worth it to pick up a cheaper mono cartridge, for mono recordings? If so, what are some good prospects in the 100-150$ price range?
Yes, I am now trying to get another arm on my VPI table so I can avoid changing the set up.
Try a Denon DL-102 mono cartridge on SME 3012 or other heavy tonearm. U will LOVE IT !
