Europa-List: Wing leveller

[William Bliss <william@wbliss.co.uk>]

Hello all

Can anyone advise on the current market/tech in wing levellers for 
Permit Europa's in UK. My instruments are mainly "steam type" and I do 
not want to change them all. I may add a pitch controller in the future. 
I have found Trio, Trutrac, Dynon and Garmin. Don't need a big bright 
display duplicating what I can already see and hoping not to spend a 
fortune. Are the older Navaid units reliable?

Thanks
