you should probably go on the PPT battledome chats for this one. The people there are very knowledgeable.

as well as the battledome chats, idb.finalhit.org is the best battlepedia around. They have prices on most of the items there, however the prices are sometimes off, so they also have this nifty function that allows you to search them on the Wizard or Trading post.

Off the top of my head though, for good cheap weapons you would pobably have to go into species weapons, they're usually less costly than non-species.

Definitely check out the battlepedia. It lists all the reccomended weapons and also show an average Shop wizard price.

Species weapons are alot cheaper and sometimes do more damage then normal weapons.
