Power Cord for Rega Saturn-R and Elex-R

Hi All - Currently I have Shunyata Venom 3 power cables for my Elex-R and Saturn-R, however I don't like how the connection to the back of the unit is so loose.  Are there any recommendations for power cables that work well with these units and don't break the bank?  I had a Rega Mains at one point and preferred the Shunyata to it btw.  Thanks very much
