Need help with phono cartridge selection

Anyone heard a Garrott Brothers p77i from Australia? They get Chakster's endorsement for the the best New cart value which has me intrigued.

I have a nag mp-200 and I am continually stunned by how amazing it sounds... I've had it for coming up on a year now and it remains outstanding (even more now that it's broken-in). 

My plan was always to start with the mp-200 so I could save a little money by using my Technics 1500's on-board phonostage (which is actually pretty decent). I always thought when it was time to replace the cart, I'd upgrade to a tube phonostage that could handle a LOMC cart and get a Hana. HOWEVER, the mp-200 sounds so good, I'm STRONGLY considering keeping my system as is and just upgrading to the MP-500. I might be Nagaoka for life...

I was bewildered why my MP-200 was sounding so thin and shrill, but as an experiment I put the 200 needle on my mp-150 cartridge and immediately the bass and dynamics were back. Not sure what's going on there, but my suspicion is that I bought the whole mp-200 with headshell and that nagaoka headshell was lighter than the standard Technics (so maybe Nags like heavier headshells?), I had to adjust the counter weight to compensate a tracking force of 1.8g. You gotta love Analog....

BTW, this whole conversation has got me researching affordable MC carts and probably the next one I would try is the Denon DL-301 mkii. I haven't heard one bad review of it and a couple vinyl rips sounded really good. Might also keep Denon in mind...

@crawfishdaddi +1 Nagaoka MP500 over a LOMC.

DS-Audio Optical cartridge and matching energizer. Try the entry level and thank me later.
