I recently ordered the Pognae baby carrier -- "the best comfortable baby carrier you'll ever wear" -- from gmarket. I decided to go with the Pognae because it looks exactly like the Ergo carrier, but is about half the price. Since I haven't been working for around 6 months, I save money wherever I can, and I had a good feeling about the Pognae. My good feeling was correct. I've only wore it out once, but it is comfortable and sturdy, and I like the design. The plain ones are cheaper, around 40,000 won, and the graphic design ones are extra. The elephant one I chose was an extra 15,000. The print material is a very soft muslin type of fabric, and the print is not garish or cheesy. There are even zebra print and military print ones! 
It's definitely an Ergo knockoff, but it has a few extra features. It comes with an extra head support that is attachable by velcro. There is also a flap where the baby's back is that you can roll down to reveal a mesh material to allow for air flow. One thing I really like is that on all the loose straps there is an elastic attached, so you can roll up all those loose ends so they're not flapping around. For an extra 6000 won, I got the sucky pads, which are quite thick and nice, and reversible.
So I'm pretty happy with my Pognae. It's the first carrier I've picked out for myself...all the others were lent to me -- the Moby, the Ergo, a Korean Baby Bjorn type carrier -- which was great because I got to try many out before purchasing one.
