I purchased a SeQual eQuinox Portable Concentrator which works well for my purposes and I don't have to deal with tanks anymore--great service too.

I'm still on the 30 day risk free tryout, however, thus far it's been good. A little noisier then I thought it would be and also heavier but it does give me the freedom to go where I need to which is very important to me. I also like the two battery packs as you will almost never run out of oxygen unless, of course if you forget to charge your batteries.
