This has been covered many times. Here are my rough numbers:
ADS-B TXP $3,500k (say)
New grayscale encoder $1k
Engineering orders (say 2) $700
New TXP antennae $500
Installation (est) $3k
Total: $8,700
if your GPS is NOT WAAAS, add
secondhand Garmin 430W AUD$10,000 (if you are lucky)
New GTN 650 maybe AUD$20,000
Plus new antennae wiring (required) plus engineering order plus rack re-layout & installation, say $5k
Pretty much backs up Leadie's numbers
