Just my 2 cents. If you can get this one, you might want to check it out. Going price is around $370 or so right now. I have used the XS Scuba Tri-Metal SeaAir for several years now. IMO, can't be beat for the price. It was THE best breather in any price category when hooked to breathing machine and tested by ScubaLab, best buy, top muscle reg, etc, etc. I love mine and can notice no difference b/t the surface and 130 feet. Extremely solid construction. This had the top scores in every category when tested... very solid buy in my eyes. Personally, I don't mind shipping mine off for annual testing. It's only a couple of weeks out of my dive year.

Extreme Performance
The SeaAir Tri-Metal regulator provides the performance of today's most expensive regulators, yet is moderately priced. There is no better value. Manufactured from stainless steel, titanium and brass, the SeaAir uses the metal best suited for the job. Factory cleaned and ready for pre-blended Nitrox up to 40% FO2. Engineered to deliver the most air at all diving depths, and with just two simple turns of the adjustment control knob, you can quickly de-tune or fine-tune the second stage.
