I called and talked to a guy at the shop where I intend to buy the resistance rollers, the Sportcrafters ones.

Found out something cool...they work in conjuction with Trainerroad to give you a fairly accurate wattage output feedback as long as you have an ANT or Bluetooth speed/cadence sensor.

I am planning on getting the Garmin Edge 500 I think, but to use with the rollers it looks like I could just buy the speed/cadence sensor now for using with the rollers, then get the head unit when spring rolls around :-). I already have a Bluetooth USB dongle for my laptop.

Bluetooth vs ANT keeps tripping me up, I would need an ANT dongle....not a super big deal, another $25.
