If it were me, I wouldn't expect any huge discounts at SnF this year from many of the mfgrs...but...what I would expect might be some really nifty and neat new products, expanded functionalities, features and enhancements from a lot of the people out there.
Good example, TruTrak is now shipping the Altrak "VS's" and Buttons completely assembled..which removes the requirement for the customer to install those pesky little resistors onto the buttons, AND makes the installation of the Altrak entirely and completely PLUG & PLAY...the only thing you have to do is hook up the Servo, run a red wire to power, black wire to ground and the static line to the brain box! Things like this will only get better as products and companies mature.
You'll find that there isn't a huge pricing difference in things like Autopilots and EFIS's as you go shopping for several reasons. Margins aren't huge, MAP's, Inventory, etc.. You may very well spend several hours searching to find only a few $$'s in price difference. As with everything, it's best not to buy from the absolute cheapest, nor the absolute highest, but somewhere in the middle...at least that's my philosophy!
Just my 2 cents as usual. SnF should be REALLY exciting as far as the Autopilot, EFIS, Engine Monitor, GPS and Avionics world for us Homebuilders. More new stuff coming this year than I've seen in awhile.
Cheers,
Stein.
