Browsing is inevitable if you want to get a sense of the market prices.
However, now with the search system implemented, you can compare specific item prices pretty quickly, since retainers with the searched item will be highlighted with a red star. You just have to select the proper category from the item search counter. If you cannot find your item, congrats, you might have a monopoly. Do not make your items outrageously expensive and chances are they will be bought.
If you can obtain npc selling price, about half of that price is a good start. npc items are generally pretty overpriced.
Or you could /shout or get a linkshell. Can't guarantee it would be more effective or faster though. I suggest you start at your server forums.
