RX400 Leather damage: Replace seat cushion or...

[Pnuma]

I have leather damage on the driver's seat of my RX400 on both the bottom and back cushions.

Pictures shown below.

The process of replacing just the leather seems complicated to me. I would most likely be having the job done by an auto upholstery shop. I'm uncertain how much that would end up costing, but I assume it wouldn't be cheap.

However, I ended up finding an entire drivers seat in good shape from a salvaged RX on eBay for around $300 - $400. It's described as being in grade A condition.

My question: Which would be the better way to go? Which is cheaper? Which is easier?

I personally would start out with the second hand leather but have an upholstry shop install it. 

If you end up not liking the results, many people swear by 'leatherseatsdotcom' for new covering(s).
