Looking for hardware Avionics.

I am looking to purchase hardware avionics. Any suggestions and ideas?I have been looking at this ITRA Avionics. It costs around 800Euros + 50Eur for shipping,http://sim.itra.de/default_en.htmI currently have Flightlink's TR-1. Its a nice unit when it works..but the USB card in it has been giving me grief. The unit keeps freezing on me.. and getting out of Fsim and getting back in brings it back on after a few tries. I bought a new USB card for it spending about $300 bucks to fix the freeze issue and now it has started doing the same.http://www.aviationsimulation.co.uk/acatalog/Avionics.htmlI have a few Go Flight units and those seem to work fine. I like Go Flight stuff. But to get Go Flight units for everything that the ITRA radio stack provides, (2 Nav radios, 2 Comm Radios, 1 transponder, 1 DME display with NM, KN and MIN., 1 ADF, AutoPilot Autopilot with ALT and VS display and the functions AP, FD, APR, LOC, LVL, Y/D, NAV and HDG) it costs lot more than ITRA as a whole.Anyone with ITRA, got any feedback?any ideas?Flight Illusions announced a nice one..but so far its vaporware.http://www.flightillusion.com/oldnews2.htmManny
