Where do I need to shop to get "good" XHDs?

I've settled on getting a pair of passenger-side XHD style springs for my wagon. The low arch and spring rate is about what I need for my street handling goals.

It looks like the place to go for Canada-made/not-Mexican springs has been Mancini. Is that still the case? Are there other vendors I should shop? I'm afraid of getting a dud pair and sagging inside a year like some folks have reported.

I've heard nothing but good about ESPO Springs and Things. Thats where I'll head if I need new leafs. Plus they are a Moparts sponsor...

Would you have a local spring shop? Maybe look at changing all the leafs below the main springs?
