We used Form Kitchens for ours and we're happy with the outcome. Seems higher quality than Ikea. Total was ~$25k for just the cabinets, minus ~$5k refund for late delivery.

Our kitchen is 18'x10' L shape with 8' island. Appliances were ~$9k (we bought them about a year ago). ~$13k for 3cm Silestone countertops with 8.5" tall backsplash.
