The Mini Quad is a very nice Low Cost option IMO . and for just about $.75 a ft you can move upto Sliver clad Copper cable which will be next for me.
I just got done building a set of mini's (which will prolly end up in the yard sale after I finish the silver clad's.)
Next will be 99.999% silver IC's .. Litz braided .That will hopefully look something like this
