Who is you go to for top quality vinyl

Shogun.

You wouldn't recommend visiting Osaka? I heard it is a funky city, Japanese style.
I buy very few records, almost all original Japanese pressings. I take a risk on ebay, so far only a few records were a little overgraded. In one case the man who sold it to me said to keep the record and refunded what I paid for it including shipping. Shipping from Japan is expensive, about $15 for registered airmail. This is fine with me.

I've never done it , thats a few week wait also correct? 

As for japan , I have not my parents lived in okanowa in the 50s (Airforce)
I just get so nervous with used lp i have had just one after another be atleast one or two ratings below stated . Not always like I've stated  before I am rebuilding what was an extensive lp ,cd collection lost in a fire ( cds just never seem to be replaced anymore) . I just get lp ,which is funny because i went nuts on cd collecting in the early 90s 

Oleschool, regular registered airmail usually takes about 10-14 days from Japan. I never tried economy airmail - this could be weeks. EMS express is usually $20-$25 and takes about 5-7 days in my experience. I don't buy pop music, only jazz and jazz/rock fusion. Often enough Japanese dealers specialize. They may not speak good English but usually understand English well.
I almost stopped buying from Americans, either dealers or not - they always overgrade. No reason for me to buy from Europeans. Bought just a few records from Canadians - was alright except one time.

One more thing. Japanese original pro records sound better than regular, sometimes significantly better. They can be identified by an inscription in Japanese on the label. Usually sellers mention it but not always.
