Hi Drew,
  I'd go with Ulix' advice.  Try a stock front bar first; especially
considering the prices you noted.
  My '73 has a stock front bar (with hard plastic bushings) and a very
small rear bar.  I like it.
  When I got the car it came with the rear bar and a very ugly, thick front
bar.  Neither of which was fully hooked up.  (Really sad -couple- of POs)
  I put on the stock front bar and fixed the rear one and have been quite
happy.  This supports Ulix's suggestion to only use a fat front bar if you
are also going to add a rear bar.
  A sway bar is made of basically the same steel as a coil spring, only
straightened out! :-)  It will eventually weaken, but it would take a LONG
time.
  IMHO: Definitely start with just a stock front sway bar.  (And make sure
you get -all- the little mounting bits with it.)
