Well, since you were wanting the wire with the boxes, theres alot of wiring kits out there. You can get all you want from Painless. Yes, their products are more, but if you want cheap, go the Aux. panel route and do it all yourself. T's is often cramped for room, so I usually get things that are well built, and have a good many mounting screws.
I usually mount the panels on the back side of the dash on a hinge. When driving and going down the road, your shoes and feet won't accidently bump the block, snag wires, pulling them loose.
I get like a 4" hinge, mount to rear of dash, I leave about 4" extra wire so the fuse block can swing down. When the block is in the up position, I cut a 4"x4" piece of velcro, put it where the hinge folds onto its-self, it'll stay tucked under. I use the good industrial quality stuff, and put a counple of small screws thru the velcro so the heat won't allow the thing to fall down. That way you don't have to stand on your head to change fuses....you can sit in your seat and check things out....
Another option is a cut down thick rubber bungie cord attaching to 2 hooks, one on either side of the fuse block. Personally, I like the velcro....
I even have a LED light illuminating the box once it drops. Wait till you blow a fuse at night like I did....not fun. I'm too damn old to be standing on my head, trying to find which fuse has blown....
