I've been a MS Flight Sim user basically from it's inception. I
recently bought the cheapest Elite sim and have been poking around on
their forums. They are just finishing a patch so you can use most
Garmin handhelds with the sim. It sends all the data through the USB
port to your handheld so it's like you're flying with it. It's like 48
bukz. Cheap upgrades like a KLN94 are pretty hopeless according to
what is being said on the forums. They usually have a very expensive
solution though... Like buy a real KLN94 and patch it in.

It's somewhat off topic, but I can't see anything Elite does that MSFS
doesn't if you don't want to spend big bucks. In fact there is a great
deal FS does that Elite does not. Elite has a few approach capable GPS
units that come with the core package, but no Gamin or Bendix.

But like Elite they charge extra for everything. For 160 you get all
there IFR senerios which are pretty good practice. The core sim is
only 160 or so and it's not bad for IFR practice if you can live with
the onboard equipment. I use it to practice non GPS approaches and it
does that pretty well. The autopilot seems more realistic and the way
you use the mouse to dial in freqs is nice. Also, I think the weather
you can create is very nice for approaches and seems to work
consistantly where I find it hard to make FS do what I want. ... aKiley
