Bad idea?

Used cables are your friend.  These are excellent cables for only $425 shipping included and no cutting required.  If they don’t work out you can turn around and sell them for little/no loss so very low risk to try.

Cheers.

There are lots of good cables out there, used, in different lengths and well under your budget...
