What is a typical life span of a stylus or cartrid


I have opt to make a purchase on a turntable that has roughly 30 hours of use on the table and cartridge.
A hifi shop has it and offered me $70.00 off regular price.
Any ideas?

Thanks

By the way, I am just getting back into vinyl. I am a borderline audiophile if you want to call me that lol.
Another words I have been into Hi end equipment for 20 years. Just budget minded till now.

You know Sky- I may have tossed too many curves by mentioning the Rega and VPI upgrades. I'm a tweek/upgrade freak, so that kind of stuff holds a lot of appeal for me. If you just compare the two Pro-ject tables; you'll probably find the Xpression III more satisfying musically than the Debut(the Oyster is a nice cartridge), and save yourself some gyrations/agonizing. Again I stress: Listen to them with your phono stage/pre-amp. Matching the output and sound of a cartridge, with the gain stages of your system is VERY critical. If the Pro-ject pieces seem too lean for you/your system; the Regas have a warmer(British) presentation, and may suit your tastes better.
Project does, in fact, make a very interesting upgrade available for all of it's tables. It offers two different regulated power supplies, the more expensive of the two, I believe, is a regenerator. I have no experience with the marque, but anecdotal reports on the web indicate that these are worthwhile upgrades.

The first upgrade that you should consider may actually be a better phono cartridge.
Thanks again everyone. I will take in everything posted and think about which table I will buy.

I'm more confused now than ever lol.
Just to let all know, I thank you for your input. I did purchase the table. I saved some money and examined the table etc. It plays great and I am satisfied with it.
