collectors suggestions sure are hard :(

http://www.tf2outpost.com/trade/22228118 3 key buyout, sold in 4 days.

http://www.tf2outpost.com/trade/22228045 2 key buyout (quicksell)

Armani's buyout is closer to 3.25, not 3.3 but whatever rounding.

http://www.tf2outpost.com/trade/22298223 seller at 3.5 (2 days old)

http://www.tf2outpost.com/trade/22148189 seller at 4 (1 week old)

http://www.tf2outpost.com/trade/22131826 seller at 4? keys (not sure) (week old)

http://www.tf2outpost.com/trade/22252560 seller at 6 keys (lol)

Since the beginning of august there have been 8 sales on the SCM and the cheapest sale was $8.22 (8.22*.85/1.81 = 3.86 keys).

Cheapest on sale currently is $10 (4.7 keys)

Cheapest chem set for it is $3.45 (1.62 keys + 11.11 ref to complete = 3.1 keys)

Chem set sales for it for auguest are $2.8-$3.1 with a $3.5 outlier.

If you were bothered enough and had the steam funds, you could fill this set out for about 3 keys.

I think that 3-3.5 would be more appropriate a suggestion. Neutral for now.

edit: math for SCM: Price *.85 (15% valve fee) / 1.81 (key price) = fair market value in keys
