New / custom seat upholstery source? Or just buy new aftermarket seats? Opinions?

If i had to do it again I would go with aftermarket seats, the factory seats in my 70 duster are just not comfortable enough to justify the cost of redoing them. I did mine with Legandary covers and foam, did them 10 years ago and still look like new but just no comfort to them. Forget what they cost but I know it was way more than what a good set of new seats would have been.
