I say buy the set. Paint the chairs light or better yet, get an antiquing kit so you have some gold paint in the faux worn areas. Then lightly sand the table top to paint glossy or just use a tablecloth. Your kitchen looks like it's going transitional bordering on contemporary. I don't know about the rest of the house. If you wanted, you could go more eclectic in the dining room; depends on your layout & how the house flows. Better if you love it but I understand budgets. The 8 chairs alone might be worth the money given what basic chairs would be even at Walmart or Lowe's. Do what fits your style & family.

We've done lots of spray on - knock down, but this doesn't look like it was sprayed on - it's way too heavy for that. We also thought it was an attempt at crow's foot. You gave me a good laugh, klem1! The house is 2400 square feet with 10-foot ceilings, and this texture is everywhere! Doesn't make sense that they would've trowled or rolled it on, but we've never seen a sprayed-on texture be that thick.
