Spacer Band Help!

[galvana]

I need help and I hope someone or many of you will guide me. I have a prong set e-ring and just purchased a prong set eternity band for my w-ring, Both are platinum. Now i need to find a spacer for in between so they dont scratch eachother.
Where can I get a 1.5mm or 2mm platinum band for less than $100 or 200? I can''t find one anywhere. Platinum seems to be soo expensive right now.
My other question is, could I get white gold OR palladium for a spacer?
i have read its bad to "mix metals" but Im wondering - is that cause the white gold or palladium will get damaged from the platinum? OR will the platinum get damaged?
Honestly, Im trying to find a spacer for under $100 (as i went wayyy over budget on my wedding band

) i couldn''t help it! my fiance is very good. thank goodness!
So Im starting to think maybe i''ll just go with white gold or palladium instead of platinum for the spacer- BUT i dont want to do anything that will potentially damage my w-ring or e-ring.

Please advise!! Thank you !

I''d personally try to go with silver because A) its cheap and B)its soft.

I don't think you'd ever be able to find a plat one for less than $100. Here's a link to where I got a plain band. They are really really nice rings and cheap

If you aren''t afraid of eBay (I''m not, as long as I go in well-educated), this seller has 2mm bands for $200: platinumguy.
