If cost is the issue, then consider a smaller value VH Audio Odam. Perhaps a 1.0 uf. In the end if these are still too costly for you, then a Miflex will be better than the others you mention. Yes, I have used all the caps you mentioned.
Please be aware that the Miflex caps are huge and may not fit easily based on the value you decide on. Check for fit first. Simply look up the dimensions and make a mock up using a properly cut and rolled piece of paper or thin card stock.
