Cup for SVEA 123?

I know it has been asked before but I can't find the thread.
Of the currently available Titanium or Stainless steel cups with folding handles which one fits best and which one is the most affordable this month?
It's a nostalgia project and not going to be a serious user stove; canister gas being my go-to for that but I always liked my old stove, however I probably sold it when I bought my first MSR X-GK
