If you are in the US and want to sell that P700 ST I would pay $40 for it. Condition looks real good.
I just bought two new P700s, but eventually I will hit the edge and damage one badly enough to need a replacement. I love wearing the light, super-small eyeglasses, but for TT they suck.
If you don't want to sell of course it's no problem. Just figured I would ask since you said you have three and don't play them any more.
