It's a good question and definitely something every potential owner needs to consider. Although not a "requirement" in order to sail, there's a huge "need" to have them. I'm about to replace the electronics on my Newport and I'm looking at a minimum $500.00 if I get a basic GPS/Depth finder, to as much as $2000.00 in order to pick-up an autopilot and basic wind/weather info. And hey, I'm going the cheap route. Electronics are like anything else "big boy toy" related; you can spend as much as you can afford as I know guys that will tell you they have $10k and want to add more. Wouldn't suprise me that this figure is closer to the average cost. If you can count on them for 10 years, then you're looking at $1000 annually.
