It's pretty much black/white and the paper quality, the anthologies are printed on the cheapest paper possible because they're supposed to be thrown away after reading. The graphic novels are printed on higher quality paper, but still not as good as the paper american publishers use.
That makes sense. That was the mentality of the American publishers in their heyday. But now that it's a collector's (ie long-term) medium and they upped the quality in those areas, the price went with it.
I admit, personally, I don't mind paying the extra money for the better paper and colours and the like. But then I've got a full time job. I have no idea how I would have been able to start collecting if I was a kid starting today.
Back issue bins. Nearly ever LCS has at least a handful of long boxes in a corner, or on a table or something with loads comics for a buck or less. Honestly, that's kind of how I got into comics. First super hero comic I bought myself was a back issue. I liked it, went to the drug store down the street from my house, started buying them... course that's when most were $1.25-1.75 an issue. But when I didn't have a lot of extra spending money I'd hit the back issue bins, so what if the comics were maybe a year or two old - I was all about the value. For 5 bucks I could walk out with at least 5-10 comics in a baggie. Vs maybe 2. And nowadays I'd be lucky if 5 bucks got me 2 comics.
And why do I like 'em... quick easy entertainment. Something I read on the can LOL or during a lunch break when I want to de stress. Takes no batteries. And given that the majority of my collection I bought on the cheap, if one of them gets damaged somehow, I don't stress too much. Long ago I decided that I'm no longer going to worry so much about keeping everything in mint condition. Partially because I know that the majority of comics that I own were printed in such high numbers that they won't be worth a whole lot down the road. The newer ones maybe, but the interesting thing is, I've noticed that most of the modern comics - from the past 5 years or so are incredibly durable. Sure they'll bend and crease, but they don't just fall apart and lose their covers or pages like the ones from the late 90s used to.
