ND2 or Mazdaspeed Miata?

I'll be in the market for another Miata this year, I had a base NB a few years ago and miss it. Had a kid and couldn't afford 2 cars at the time.

This will be a weekend only car/toy.

On the fence about trying to find a mint, low mileage NB Mazdaspeed or just get a slightly used ND2 (like certified under 20k miles). If it were you, what would you get and why?

Mazdaspeeds in good shape and low miles are pushing $20k now, and at that price an ND2 for $25-$30k makes more sense I think but curious what y'all think.
