Der Maschin-WHAT?

Conservative drop, since I don't think these sell for 4.33 now. If I'm wrong, do counter the suggestion if you so wish.

Not many of these on the market, 2 pages of unpainted ones on outpost and a lot of them are part of sets.

http://www.tf2outpost.com/trade/22831013 (Unsold, but got an offer for 4 ref 2 days ago)

(There's also one sold at 4 ref on bp.tf - http://www.trade.tf/classifieds/search/Sell/Genuine/Der%20Maschinensoldaten-Helm/all/All/1 )

I haven't found any other solds.

Unsolds at 4.33 ref:

http://www.tf2outpost.com/trade/23123679 (5 days old)

http://www.tf2outpost.com/trade/23076617 (1 week old)

http://www.tf2outpost.com/trade/22815646 (3 weeks old, apparently lowered to 4 ref, but doesn't have regular bumping)

http://www.tf2outpost.com/trade/22341388 (1 month old)

Is this enough or do I have to wait for more solds at 4?
