I don't like flamewars, because they're always ensured to happen.

I regret nothing (I actually do). I'm prepared for everything (no, I'm not).

Note that I'm only incluiding non-painted Bill's

Whole first page of sellers (at the time of posting) at the classifieds are of 7/7.1 http://puu.sh/3RCUM.png

The second page has more painted ones, http://puu.sh/3RCVe.png

The rest of the people asking for 7.5 have painted hats http://puu.sh/3RCYR.png

After that there's lots of unsolds at 8 and higher.

Last passed suggestion had a similar amount of links, I believe this should be enough. There can't be more 7.5 unsolds as very few people ask for that specific amount, and since 7.8 and higher is out of the range, that's also out of question.

Don't ask for buyers, all are either quickbuyers or paying 7 keys, no more.

Now back on topic, 7.5 is not the most common asking price (neither is 7.4), and most of those being shown selling are painted. Demand for Bill's are going down, people don't believe they're a good investment anymore. People asking for higher do not sell or take very long to do so, 8 keys sellers are not listed because they're off the range, and they don't sell anymore for that so why should it matter? 7.3 is still possible (a few people being able to sell at that) so it's kept in the range.

Now again, don't start a flamewar.
