They have a pretty big selection of things and have a nice rotation of new stuff that comes in. I think their prices are pretty average compared to places (I mean, there was no price difference between them and other stores in the area when I was collecting Hawkeye and Hellboy comics). Staff is pretty friendly and helpful, and I enjoy the fact I can talk to them about many different fandoms and they are willing to see if they can order or be on the look out for something you want. They have a nice variety of events to participate in and are friendly and easy to do business with. I've always liked going there and browsing as well, since as I've said, they have new stuff coming in all the time and sometimes you can find a real gem! They have the biggest events for free comic book day, so it gets pretty crowded there, but it is usually a lot of fun.
Both Dragon's Lair stores are very clean and well-lit, and Craig and Bob and their staff can help you find whatever you're looking for. Other than an extensive collection of back-issues, they offer a wide variety of new releases as well as tons of games and toys and other sci-fi items. There's plenty to check out if you want to browse, and they're very well-organized if you only have enough time to look for specific items and be on your way. Their prices are generally less than Krypton and Legend. You won't be disappointed.
Don't expect much in the way of customer service, though. I've gone in there a half-dozen times in the past year and was generally looked at like as if I were an inconvenience rather than a paying customer, and I've dropped a lot of $ there over the years. They are well-organized but their prices are pretty high, so if you're in a hurry and don't mind paying more than if you went to Mail Order Comics nearby, Legend, or either of the Dragon's Lair or Ground Zero stores, you can probably find what you're looking for and clear out. Avoid their Free Comic Book Day sale...the miniscule discount isn't worth the wall-to-wall humanity crowding you out of the aisles while trying to get their C-list celebrity autograph while you're trying to shop.
To my knowledge, this is the only comic book store in Omaha that discounts both graphic novels (25%) as well as new releases (30-35%) as well as bag/board them for free. Doesn't matter if you're a pull-list regular or a Joe off the street checking comics out for the first time. The management and staff are top-notch and know their stuff, always warmly welcome people into the store (in a little strip mall at 118th and I Street), and will help you find anything specific that you're looking for, but will also leave you be if you want to browse. Anything you need, ask and you shall receive. They have, hands down, the best comic book store customer service in Omaha. They also have a surprisingly extensive back-issue section, though as a relatively newer store it leans more heavily towards more current comics from about 2000-on, though older comics can also be found. If you've been collecting awhile but not heard of MOC (they're pretty mellow guys and not publicity-seekers, unlike other Omaha comic stores I could mention...), or an old collector out of the game for a few years but looking to get back into it, check them out first. It's well worth your time.
The largest selection of comic books, back issues , trade paperbacks, and toys(with an entire wall dedicated to Star Wars toys) between Chicago and Denver. It is a clean, well lit family friendly store stocked with everything a comic, toy or gaming fan might want. Stop by when you are in Omaha, you won't be disappointed.
