You can find the stuff at Home Depot, etc in the electrical dept. Orange or blue.
TSelectronic.com has slightly better prices:

Also, I checked at my Home Depot when I was there yesterday. They only carry the 3/4" Carlon flexible tubing in both orange and blue. They only length they sold were 25' lengths.
Well, had my meeting with the electrician today (sans PM).
He actually made it such that I won't need to worry about adding boxes after he finishes. He showed me where to drill and how to fish using a fish line. Even suggested that I drill the holes I want now, as I can see where I want them. Then, the builder will just seal all the holes up with foam so the house passes the Energy Star Rating for air infiltration.
Even on outside walls. He was showing me a wire fisher...it looked like a thing you put down the sewar to clean it out...except it was flush and almost pointed on the end. He just said, turn off the power to the circuit, fish the wire through from the box, down into the hole in the footer (into the basement), or UP into the attic. Go that way, as it will be easier to hit the larger drill hole, than the smaller BOX hole. basically get it near the hole, then use a pair of needle nose pliers to snag the end of the fisher, pull it through. The fisher will pierce the insulation in a way that when I tape the 12-2 on the end of it, and pull the wire back up/down, it will NOT bunch the insulation. He suggested practice on an inside wall first. To get the hang of wielding the wire.
So, looks like I will be able to save all the $$ needed for the LV guy. I'll just have him put in the original future tube that he was going to put in. Then I'll have him drop an Ethernet line to my entertainment room, just so I'll have that there immediately...and I don't have to fish anything until I want to. I may as well have the media player setup (hence the need for the Ethernet line to the entertainment area from the server! Streaming movies baby!). As for adding more future tubes, since the chase was goofed up, my wife and I changed the chase on site to fit better into the house. As such, the HVAC guy and plumbing were able to fit everything in where they needed. I now have room to add 2-3 2" - 3" tubes of my own later on. I plan to open the wall in my closet and add an access door, so I can get at the plumbing in that wall, as well as drill out the floor of the second floor to get room for a pipe to pass through the chase from the basement (easy to drill) to the second floor (drilled out by using the access door), then the attic (climb up there and drill).
I'm pre-marking all the area that the chase takes up in the attic. The basement will be easy as there is a box made up of joists, the other floor...well, it's encased in a wall. So, I pick a common point, measure out and drill 3 pieces, run the PVC pipe from the basement upwards (gluing the 10' pieces together as I push it up). So, that saves me $150+ per tube, as well as $100/Ethernet drop, and $75 per box with string! Whoo hoo!
So, looks like this weekend I'll be drilling holes.
