Yeah cars are expensive now.
The original 91 Sentra SE-R back in 1990 was $14,500. I remember because I had enough for a dp on one and was going to buy one..and then realized I couldn't afford the insurance. (It was more than the car per month)
So I bought a '80 RX7 instead for cash.
Mine are wired for video and audio.. But only video is active. I'd rather run one cable per camera than deal with batteries.
Install once and forget it.
I installed 12 Sony color infrared cameras and a 120gig hard drive at the shop. Been running flawlessly for 8 years. Data saves 10 days and then the oldest is over written by the newest.. Very cheap to DIY.
NAD 3225pe or 3020 integrated. (3225 can be had for $100.. Great integrated)
Or an old silver face pioneer 6550 or 7550 or Kenwood ka series integrated from the 70s... Warm, powerful and bullet proof
Yeah the loose feeling goes away. Titanium is used because of the ability for human tissue to fuse to it just like bone, as it does it'll feel more natural
Glad you're progressing well Mike, I don't miss those weeks of recovery from that!
