Yes, I agree the Blue Circle power cords are very easy to work with. The easiest of any I've owned. I think the BC61 retails for around $110 new.
Any of the Virtual Dynamics power cords such as the Basic or Power 3 are excellent for the price and should be under $100 new, but unfortunately are very difficult to handle. They're almost like monstrous pipe cleaners. Still a great bargain however.
You might want to look into the VH Labs Flavor 1 power cord. It is specifically designed to be used with digital equipment. I use a Flavor 4 on my amp and like it. You can save more money by buying the DIY kit from Chris Ven Haus and making it yourself. I did this with my Flavor 4.
The Absolute Power Cords definitely fall within your budget as well. In my case however, I did not perceive any difference between them and the stock cords.
