I have nothing but positive things to say about my dealings with Stern, JJP, and Spooky. All of them delivered replacement parts (some well out of warranty) within a week or 2. Just basic plastics, or steel doo dads - never had any node board issues (those are tough to get).
I always was extra kind to them in my emails saying please and thank you's and always stressed that I appreciated their time in helping me. A little kindness can go a long way in todays world. Worked for me.
