Seeking advice on the best course of action.

I have 4 bent OEM alloy wheels that cause a mild but annoying vibration at 65-80mph that is not corrected by dynamic balancing. Braking at these speeds produces an unpleasant pedal vibration which was not improved by new rotors and pads.

Wheels have what looks like pothole type dents on the inboard side of the rims... and yes, on all 4. Car is a 2006 Sentra 1.8S and is in good shape in every other way, mechanically sound, 160k and is about to participate in a cross-country move. I hope to keep it for as long as feasible.

My options, as I see it:

1. Do nothing and ignore the vibration. If the ball joints/tie rods wear out, deal with it then.
   
2. Buy two new OEM-like rims for the front ($140 each plus tires or at least M/B)
   
3. Buy four new OEM-like rims
   
4. Buy four of some other rims that are hopefully more dent-resistant.

Option 1 is free for a while. Option 2 is at least $300. Option 3 is at least $600, etc, plus I'll probably want to change the aging tires, so then it's over $1k.

Questions:

1. What's the best course of action? Am I missing some other risks if I do nothing?
   
2. For option 4, are there more durable (and cost-effictive) rims?

Many thanks!
