Super Soaker Central

How much can a monster Xl fetch and where can they be found. Please answer.

Well, according to Soakologist's article, linked at the bottom* of the post, the most recent edition will cost around $100 to $160. I assume, however, that you want the one that earned a spot in the Guinness Book of World Records for the largest water gun ever mass-produced, which is the 2000-2001 edition, and that will cost normally up to $185.

*heh, heh, I said "bottom"

Soakologist's guide, along with nearly every article on the site, is massively outdated. I believe recent eBay auctions have had the Monster XL going for $250. Not worth it.

The guns are big and clumsy, and quite underpowered.
