The reason I don't recommend it is because this P/N has been discontinued by Grundfos. Otherwise, it is a good quality recirculating pump. They will last for many years if installed correctly.
Value wise, you have to shop around because the price spread is considerable. Wherever you purchase it, though, be sure you understand the Return Policy. Restocking fees can be significant.
For what its worth, I had to purchase this particular pump because the system was already plumbed for it. Re-plumbing would have been a nightmare. Otherwise, may have considered a Taco brand as well.
