What I like about Sherwood is that they are relatively inexpensive, absolute workhorses, and very easy to service. I have had a few over the years that I bought used, serviced, dived them, then sold them off. One of my Bruts is being used by a guy who cleans pools to supplement his income as teacher. He's been using it for going on five years now. He said once it starts to act up he will either have me throw a kit in it or buy another one.
The SR2 seems to be getting some decent reviews. The original SR1 was a piece of junk. They had so many problems with it and had to redesign and fix things in it that I'd take an old Brut over a new in the box SR1 any day.
The Brut, Blizzard, Magnum, and Oasis are all excellent regs. Now that they are all balanced as well. The Sherwood dry bleed system means that they are all environmentally sealed without spending extra money to get them packed with Christolube.
If you have a tech that knows what they are doing, and tunes the reg properly, the average recreational diver will not be able to tell the difference between it and one costing hundreds more. I don't have any of my Sherwoods left as I have gone all over to HOG.
If I had to start over though and I could not get my HOG regs, I'd look to Sherwood before ScubaPro or Aqualung/Apeks as I don't like their policies and feel they are over priced. Atomics are great regs but too expensive for me as I'd need to buy 6 of them to start with for the diving I do. Zeagle was one I'd consider but since Huish took them over something just doesn't seem right.
