IPD blew me off a couple years back when one of their much-vaunted blue poly alternator bushings failed on my 940. I got no response to my requests for help and I did not feel like calling directly.

I've had generally good luck with their products, but they have a mixed record for responses when I had had issues. This has prevented me from buying pricier items from them. I buy my poly bushings from another source as a consequence.

I will say that they did accept my return of 7 of those scan-tech suspension bushings many months back but did not give me any response when I said I could not locate the poly bushing on their site (pre-reorg) and was disappointed that they did not disclose that they were selling scan-tech products.

I'll order things like neoprene valve cover gaskets and oil-pump rings from them, but I get all my basic stuff from the other online sources.

I've had good luck with Skandix, but their product catalog is pretty small.
