agreed. have mine up for 2 keys for a day now.

agreed. the supply is constant via the mvm but i cant say the same to number of people who wants it

I think the community should work to push silver botkillers' min. value to 3 keys each. With a fair trader 1 key can easily buy two tickets for Mann Up, if silver botkillers were considered to be worth 3 keys then a tour of duty in Mann Versus Machine would result in the means to finance a following tour. It would be great boost for the Mann Versus Machine community. Edit: Also, if they were universally considered to be of such a value they would be more sought after, as a display of wealth and as currency themselves, playing the role of interim denomination between key and bill's.
