Market,
One thing to bear in mind is that the things people post in this forum are normally so far away from reality, its got little predictive value at all. This has no apparent or obvious relationship to their actual ability to accurately value a domain name, as you will quickly learn.
My personal opinion is that much of the time, what they are posting is what they would like to PAY for your name, if you were to lose your mind and offer it to them.....since almost everyone here is a reseller/speculator.
It would be like driving your car onto the lot of Willy's Used Cars and Pet Toys and saying "hey, whats this worth?".
What do you expect Willy is gonna say about your car?
Based on observation and personal experience, an appraisal request in this forum , more often than that which should occur randomly, generates responses that deviate from each other by a factor of 100, like yours ranges from 100, 200 to "low xx,xxx". On this basis, you could employ a random number generator (or a Ouija board or Magic 8 ball) and ask it to return values between 1K and 100,000 and it would be as useful to you.
Alternatively if you get enough responses so that you can throw out the high and low values you will be left with a cluster of responses which are more than likely due to the "me too" phenomenon instead of being the result of independent analysis. You can derive this from the fact that you will seldom see the extreme values posted at the end of a thread that had a lot of replies.
My advice, if you believe any name you own to be worth more than low to mid xxx, would be to get a professional appraisal (2 or 3 would be even better). Average those and see what you get.
