I think more than one guide is always good, so I don't think this is a problem.
But, I would suggest you outline what methodology you are going to employ, that way people can know how the data was gathered. I believe when F L A K E was trying to do his guide, he was trying to do a different method from Sholee.
Having said that, the prices on both guides became very very similiar after a while. I think it ended up that way because there's only so much data points you can gather, i.e., the sales you see out in the open and what people report back to you on the thread.
Once you do this for a bit you will see the dilemna you get into: 1) do you try to report what is currently going on in the market (whether it's by averages, ranges, etc.)? 2) Or do you try to incorporate a little bit of predictive/current market price range? (stock brokers do this too. That is, let's say the very last time Google stock sold, it sold for $200 per share but several months have gone by... and you feel strongly that today, if it were sold it would go for $300, do you report the last sale of $200 or the current "value" of $300?)
Sorry for the rambling...
Good luck! It's a lot of work...

Oh, one last thing... I think some of the response you've gotten is because of the title, i.e., "... "non-manipulated prices". That can be construed that Sholee's guide is somehow the result of either her manipulation or others, and that may draw some ire.
Having run the guide for a short while, its my opinion that it's actually hard to manipulate prices when there's been a long history of prices. For example, the sales of blue feathers goes back years, so for one person or even a group of people acting together, it would take a lot to manipulate it. And I've seen plenty of people try! For the newer collectibles, it's possible but only for the short while, over time things stabilize.
