there not cheap, kinda the reason why guys on here soilder there terminals, i got 5 tsunami pure copper with 24k gold plateing for $20 at a local shop, n aint much cheaper anywere else, but there tough as nails tho
and another thing, u get what u pay for
but if u want the cheap way out, get some 1/2'' copper pipe, cut it off, mash one end, and cut it in a round, n then bore a hole in it, might be cheaper, ive seen ppl do this alot with welding n what knot so i dnt see how it wont work here, bout the same thing
