I'm not too hung up on dated websites. I can understand why many sellers find updating their sites prohibitive. I appreciate the simplicity and functionality of wwcomics.com, comiclink.com, mycomicsshop.com, highgradecomics.com and others like them. They are dated, yes, but for viewing pages and pages of thumbnails for someone with thousands of comics and related print in inventory, they work great. These sites are generally tabular and have good search filters and a deep inventory.
But some of these especially bad ones, whew boy. I think they copy pasted text from their print catalogs and make haphazard attempts at adding pages and home page updates.
