Barlow's Tackle here in Texas has both Nickel and Gold in #7. You can order online at their website. Good company to deal with and usually fast shipping.
Not certain but I don't believe that Hildebrandt offers a #8 anymore, and looks like they may drop the #7 also. If you use them a lot you might want to stock up while they are still out there.
Let me know if I can help.
