My 2 cents -
I think your power cord budget is good for a solid performing Shunyata Venom HC v1 or v2. Great bargains used.

On the power conditioner if you can go up a little $-wise, try an Isotek EVO3 Polaris. See listing at the Music Direct link below. MD is great to deal with and have a very helpful return policy.

I would live with the Polaris and stock Isotek cord for a while, then try a Venom HC.

I purchased an open box Isotek Aquarius from MD and was surprised by the difference it made in my system (despite 3 dedicated lines). Truly like a component upgrade. Later, replacing the stock Premier power cord with a Venom HC made a significant difference for the better.

Be aware the Isotek conditioners take a C19 plug.

^^^ work very well for me ^^^

don't hurt me please... 

I would stretch a little, get the Decware, and consider it a long term investment in a high quality component with a lifetime guarantee.
