Totally depends on the figures. If there's 70% City/town, Atlantis, Power Miners, etc., then no, I wouldn't go near it. If this has more top shelf stuff like it was from a collection, then this would have my interest. Then you start talking about condition/completeness of the figures. If there's a bunch that have cracked torsos, then this gets even more questionable. My Bricklink store focuses on figures and their accessories, so these types of lots are of interest when I run across them(just got in an $1100 lot of Star Wars figures yesterday), but I have a checklist of questions to myself when I look at them and the lot needs to check them all off before I pull the trigger.
Usually, when there is a lot this big, the condition is all across the board as the age of the figures is all across the board. If the pictures don't show very well what is included, there is usually a reason. It can be tough to photograph this much stuff, but I generally stay away from lots that are just a pile since the middle is generally '80s town figures.
