Andre,
With few exceptions, any regulator that you will buy from any known brand will work for recreational diving. If you go to
ScubaDiving.com | Scuba Diving Magazine you can look in the gear section and find the few (and I mean
few) regulators that perform poorly at recreational depths. Zeagle is a great brand, and they do not make junk. They have great customer service, you can buy them online with a warranty, and right now they are 30% off. Who cares what most people dive? I have several regulators right now which I actually dive regularly that are from the 1960's. If you rinse it, and maintain it, pretty much any regulator will last until you are too old to dive it.
FWIW, I bought Zeagle's N2ition computer when the 30% off sale happened. At that price, it was cheaper to buy from Zeagle then Leisure Pro. I say check the ANSTI test results on the regulator from Zeagle that you like, then buy it if the results are positive.
I really must say that picking a regulator is pretty easy. Unless you plan on diving air to 190 feet or something crazy, pretty much any regulator will meet your needs. Find one that is not overpriced, and gets good test ratings. Regulator design has not changed greatly in the last 30 or so years. As a point of reference, the parts kit that I use to repair my 1975 conshelf regulator (Aqualung) is the same one that fits in the 2009 titan regulator (Aqualung).
It is also interesting to note that you cannot purchase factory authorized Aqualung or Scubapro products online (meaning you will get bent over on the price), but you can purchase Zeagle products with a full factory warranty right off the internet, for a substantial discount.
