What do I do with these Cartridges

Hello all,
I've got a couple old Cartridges, a Sumo II MC and a Dynavector Ruby. On both, one of my wonderful children broke the cantelievers some years ago. Today, I listen to mostly computer audio and I have replaced these with an Audio Technica AT440MLA. It is fine for me these days.
Are these worth having repaired? Better to sell them as is? Not worth someone else to buy as is? or a No brainer, YES, get these repaired.
I haven't followed cartridges closely over the years, so I'm fairly clueless of their value. Thanks for your help, Tim

The Ruby does not sound anything like a 17D. It didn't when they were both brought out(23R-$310.00/17D-$650.00), and the Diamond has been improved, more yet, as of late(17D3 version). Damaged Karat Rubies bring about $50.00(average) on eBay. The Ruby was a good cartridge. The Diamond was/is a great one.

Thanks so much, all good info. I'm thinking I might start with the Sumo and tackle putting a new cantilever on it myself...

@Timlub- Here's something that you may find of interest: ( http://www.vinylengine.com/turntable_forum/viewtopic.php?t=22847 ) Personally; I would find something more rigid than a cactus needle, though weight is certainly a major factor.

Thanks Rodman, you might remember Marcof Electronics, years ago I was general manager there, we made moving coil head amps, speakers, cables & modded phono cartridges as well as amps & preamps.
I have laid my hands on (modded) a few cartridges over time. I think I can do this competently. I've read the vinylengine article before, If I recall, they did one of the Sumo cartidges there. I truly appreciate the responses. Tim

Just read my last response, when I said I think I can do this competently... I wasn't being cocky, I hate to come off that way...I was saying, Uh, I think I can do this, Kinda like the little engine that could. Might not have need this explanation, but... you get it. Overall, I'm quite worried that even if I get a cantilever with the correct mass and get it somewhat similarly damped and get it mounted straight, that it will even sound remotely the same, its easy to get peaks or dips through the cantilever.
