I've said this time and again, and will yet again! :-) I agree with Steve and others - Record Research Labs fluids are the best for leaving no sonic signature and, as Steve points out, there is seldom need for multiple rinses as with some other products. So, while they are not cheap, they are realtively cost effective - at least for me.
If the larger sized RR bottles are too unwieldly for you, buy a smaller bottle first or buy a simliar bottle of any other liquid, thoroughly clean the bottle and then dispense into it from the large size RR container. If you are really having trouble finding an appropriate bottle, e-mail me and I'll send you one.
