Received two records from the States today, graded as VG that should have been graded knackered!
My experience is that UK sellers are much more up front and conservative in their grading.
A lot of amateur ebayers know bugger all about quality and just see $$$$$$ when it comes to Soul.
Records graded Good ish, are virtually worthless to sell on so I find many go for the soft option and grade VG or above .
After all with postal prices now being what they are, it's easier to take it on the chin, if you bid and your bargain turns out a dud.in.
If you've got the dosh, buy from Anglo, Moerer or Manship go for quality if you can.
Sorry just my experience, buying on a limited budget.
Interesting thread though.
