Leather seat installation (if, where, and how much) around the Baltimore area

I have wanted to install leather seats in my Prius for a while and I'm thinking of doing it now, even though I've had the car for 6 years in April. I'm relatively bored of the car, but it only has 62k miles and I don't see buying a new car as an alternative.

If anyone know of a good leather seat installation store in Baltimore, has any experience about how find a good one, or has a good/bad personal story about such a modification about their I'd be thankful for their suggestions. I've searched the forums here and seen many pics, but any newer discussions with experiences after years of ownership would be good. ShopSar has them for $749, which is a decent price.

Also if anyone knew whether I'd totally lose the added value to the car in case of a total loss, that would be helpful.

Thanks!
