Grading raw vintage cards for trade or resale purposes

[obcbeatle]

The newest SCD catalog I have is from 2009. Is it safe to say that using the grading guide in that SCD is still sufficient for purposes of grading raw vintage cards for trading and selling? Or are there newer grading guides these days for cards? The reason I ask is that I'm seeing a LOT of TPG graded cards that look VGEX to me, but are graded Poor. Many are posted/pictured here in threads re: "recent pickups", Pre-War & Post-War. I understand that TPG grading can be very harsh, particularly lately, and I understand that their grading can be all over the place, which sort of negates one of the reasons for even having TPG's. But it makes it awfully hard to consider a grade for a simple raw card when considering trades/selling these days. Particularly in the VG, VGEX, EX condition area. And yes, I know everyone has their own opinion on what grade a card should be, e.g. the seller almost always thinks his card is a higher grade than what the buyer perceives. It's human nature I'm just looking for a standard relevant go-to grading guide for raw cards. Bottom line, what guide are raw card collectors using in todays world?
