Neither do I, and I wish I did.  There are masternode hosts which seem pretty cheap to me on a per month basis.  I checked the earnings calculator the other day for how much you can earn with a Dash masternode, and it isn't a really large amount given what Dash is currently trading at.  It was something like 5 Dash/month for 1000 Dash as collateral.

Dash isn't a staking coin, by the way but I think you know that.  I'm not sure I'd participate in a masternode pool if those exist.  It would be much more profitable (I think) to just stake another coin like Neo, Navcoin, or pivx.  At the very least you're in control of the staking and your coins.
