My brother just imported 10 of these pumps for the same reasons several people have outlined.
I personally purchased 2 of the brown Herm-It pumps from Nev a few months back when the $32.50 price was on offer.
I can't see any difference visually between the 2, except the sticker. The after sales support is probably better though.
Anyway - back to what I was going to say, I bought stainless fittings from Keg King for my pumps. Their 1/2" NPT fittings work really well with a few turns of teflon tape to improve the seal.
I have a mix of their 1/2" nipple (whirlpool arm and transfer to fermenter) and 8mm nipple fittings (for 3/8" stainless wort chiller) as well as their 1/2" quick connect fittings. All work really well.
Aside from the pump base on one of them breaking, the pumps have worked like champions.
I have missed getting in on this buy but would really like a similar pump that has a better flow rate at a higher head height - 5-8L/min at 6m head would be good (I want to pump water from a holding tank back into my water tanks that sit about 5m above the brewery). So maybe the 24V model may fit the bill, either from Nev or a BB if they are not being stocked.
That is all.
