I agree with the two previous posters.. with the poor CS you've gotten, and given some of their other "business tactics", although I quite liked the Ergo I had I wouldn't give them my business again.
There are plenty of other small companies that make SSCs, and loads of WAHM-made SSCs out there as well (two of my favorites - Kinderpack and Dream Carrier - are made by these dedicated mamas, although they can be hard to come by since it's just one mama making them all, with maybe a little help). I also think it's kind of cool that the mamas who make these carriers are available to chat on their FB pages or on thebabywearer if you have issues with using your carrier or if you just want to let them know how much you love it

You can find plenty of used SSCs on the For Sale or Trade forum at thebabywearer, and there are a number of WAHM vendors that sell various SSCs too.
If you liked the fit of the Ergo as far as waist/shoulder straps, the Olives and Applesauce SSC (another WAHM-made carrier) is the most similar carrier that I've tried. Except it's prettier and not so hot (not heavily padded like the Ergo), and the body comes in two heights (16" or 18"). I think Sweet Pickles usually has some in stock.
