Jeep Cherokee Forum - Electrical Issue.. Need help...

Alright guys well my jeep started poping fuses and dying driving down the road last week and has been in the shop ever since (I gave it about 4 hours and gave up.. if I continued down that path I would have no glass left and tons of broken tools). Today they found out that the problem started in the Junction/Fuse Block down by the passengers feet (it is all melted and stuff) so we called Jeep and they told me it cost 600dollars for a new one... So my question is this... does anyone know where i can get one online or what years I could pull one from in the junk yard? Thank you! I really dont want to shell out 600 bucks for it....
