You're right, it is indeed your choice. We all have choices.

If you would prefer to call a toll-free number and receive fast service (albeit not as skilled) from a conglomerate call center, then you're better off buying from a larger company anyways.
Quite frankly, the only thing "flame-worthy" in your post (IMO) is how quickly you've decided to pass judgement and form your patronage decisions based on disappointingly limited information. You've already formed and trumpeted your "unimpressed" opinion based on a PARTIAL part number you found through an internet search?
Yikes.
Personally, I could care less if you buy from PRG Products or some douche down the street. I don't own stock in Greg's company. I just enjoy passing on information/ modifications that have worked for me and vendors that actually use and install their products. Getting support on an install at 8pm on a Saturday - that's HUGE. A large part of my life is devoted to vehicles, so I may come across stuff that's worthy of sharing. These springs are by far
the most cost-effective mod I've bought for this truck, and I've invested more than 50% of the truck's MSRP in aftermarket additions. You can choose to spend your money as you see fit with vendors you deem "trustworthy". I don't know anything about the Alcan springs, but I'm sure you'll be happy with them and the service they provide you. Best of luck!
