I was planning to get them thrown on too.
When I checked the SRD, it said they were 1/2 of the the cost of unlimited, so in essence, it would be closer to the following:
5000/3=8333 gp+1/2 8000=12333 gp.
Throwing on Bracers of the Hunter would cost either 8500+.5(8333+8000)=16666 gp, or 12333+4250=16583 gp, depending on the order you apply them...
Thanks guys, you've been a help.
