Should I buy a VPI SCOUTMASTER. I OWN 25 RECORDS.

If you have 25 records why do you need VPI SCOUTMASTER belt drive ? As i can see even second hand VPI is about $2k, right ? Look for new Technics first and compare the prices, it is direct drive.

Never buy an MC cartridge if you never tried a good MM before, read this article first. Start with MM or MI cartridges, because when you will destroy some MC you won’t be able to replace the stylus yourself. Stick to under $700 price tag for a cartridge, buy Moving Magnet or Moving Iron. Check Garrott or SoundSmith if you need new production. Audio-Technica cartridges are always good! 
 Some vintage are excellent too.

Grado still makes the best MI cartridges!

You don't have to spend that kind of money to get going.  All the fuss about turntables is, in my opinion, tweaky and over blown.  It's a pretty basic function.  My suggestion would be you a Pioneer PLX-1000 turntable and one of the Hana cartridges.  That will run you around $1500, depending on which cartridge model you pick.  Sounds like you may not need a phono pre-amp, but if you do, search around for the best one you can afford.  My opinion is that the cartridge and the pre-amp make the most difference.  My experience is that with a good cartridge, the pops and clicks are not so bad as you think.

 In any case, definitely go for it!  We stream and do digital music production all the time, here at my house, and have solid gear.  but nothing sounds as good as vinyl.  

Hanna MC cartridge owner should explain what would you do when your stylus is worn after 600-1000hrs of use if it's Shibata or if you will broke your stylus/cantilever accidentally? 

beware of ideologues. MC vs. MM, digital vs analog, direct drive vs. belt drive - all depends on the implementation, not the format per se. 

choose the one that gives you mental energy and focus.  

for god's sake forget about the pops and clicks. A decent phono stage will eliminate 98% of them. 

VPI tables AND tonearms are a very good value. Unipivots can be set up well.  

good sound will always be expensive.
