You get about 80% of the value from the $30 models on Amazon that don't require electricity. I wouldn't let that hold you back.

They don’t always require electricity. I heard expats in Bali refer to the popular style there as the “bum gun”, which is basically like the extendable faucet in your kitchen sink, but for your butt. Just needs water pressure.
There are simple unpowered bidet seats for $25 or less that anyone can install in 15 minutes.

You don’t need electrical lines. Check out companies such as Tushy.
