I have 2 S5's for sale that are hosted by Lee Group. Hosting cost for each is $1.416/miner/day (about $42.5 per month). I've had a bunch of miners hosted there for months with no issues, and will still have miners hosted there after selling these 2. These include a PSU (not a rental - you actually own the PSU).
Check the thread here -
https://bitcointalk.org/index.php?topic=934581.0$375 ea. with hosting paid through July 20. Escrow can be handled through the hosting provider if desired.
You can set these to mine at your own pool and check up on them through their online interface.
If you don't want them hosted, Lee's group can ship the miner and PSU to you - you will have to check with them on cost, but it is quite pricey to North America at least.
