TT31 (with
ADS-B, but twisty knobs) is £1850 from Harry M as full install kit and £1815 from Harry using old KT76A tray (as direct replacement)
Garmin GTX328 (no ADS-B) £1799 from Transair
Garmin GTX330 £2595 from ASG (this is old pricing - same as it was when we were looking)
US price = $3595 (Aircraft Spruce / Chief / others) @ £2250
Price via our avionics guy is £1700 for GTX328 and £2300 for GTX330 (currently)+ install and Mod (EASA) paperwork.
If VFR only (and not really bothered about ADS-B yet), then GTX328 is the one.
For the European position see:
EUROCONTROL - General Aviation - VFR Briefing Room
Anyhow, bored myself now
