If you can go with USB which is a little bit more flexible, Sundtek SkyTV Dual might be something for you.
Although we have a low profile dual DVB-C/T/C2/T2/S/S2/S2X PCI-e in the pipeline as well, while the FPGA PCI-e part is ready we are still working on the frontend part.
Our devices are fully supported with libreelec.
Yes an external powersupply is needed for the Dual DVB-S/S2/S2X tuner - it's required for the LNB and/or Rotor.
The Single DVB-S/S2/S2X Tuner will try to use the power available from the USB port - but there are only 2.5W available so it very much depends on the satellite system itself.
By the way 12V can also be taken from the PC system itself (eg. harddisk connector)
PCI-Express devices are in progress, we don't have them on the market yet but they will be available within the next 2 months I would say (according to the current status). Contracts with chip suppliers are signed, samples are in our office. The PCI-Express datatransfer already works, we are working on the frontend (receiver part at the moment).

There is a definite need for 'supported' products in this space so this is nice to hear
