As far as I know they're just your standard low quality bikes. The higher-end brand here is Elfama I think, but even then you're probably better off going with a foreign bike. My local shop sells a few of the Korean brands, but all their quality stuff is imported pretty much.
I guess it depends on what you're looking for in a bicycle? What kind of bike and stuff? The nationwide bike chain Samcheon-ri sells them, and they even have a section in my local mega-mart. Looking at their site, they can go from 100-2,000 dollars depending on the bike. Everyone in Korea I've talked to about biking has told me to pretty much just ignore the local stuff and get a non-Korean bike because of the quality differences. I can imagine importing one would be even more expensive than they are here.
Kinda need a hybrid for commuting. I think I'm interested in the Alton hybrids because of the looks. I live in Australia and unfortunately we don't have anything that looks as good as the Alton bikes imo
They LOOK good but the quality is low. Dual pivot calipers are ok, but many ship with single pivot which sre wlrse than useless. Bearings are average at best. You are better to just flatbar a roadbike and call it a hybrid.
