The Secondary HSI RHCs are close... minus the Arc Yellow. Other than that I don't think anything else shares that color combo, definitely not in quantity and cheaper. I agree the AS $5 is not cheap but will hold up much better than an RHc option.
Seems like you are building a Taj Tribute set... and thoughts to what you plan to use for the $25 yet? Going to make a frac also?
Good Luck with the Hunt!!
