i have a tks system installed by brian alley(304-395-4932) on my
propjet.  it is a sleek installation and a tried and proven system and
when done right does not seem to cost much in the way of speed.  i saw
313 ktas at fl210 this past weekend!  i have no experience with the
other systems but for a proven "get out of jail/ice card" i did and
would stick with the tks system.
