I'm considering buying a BTR. Two companies have given me prices of about $1000, with 128K. Anyone have experience with this?? How long of a program will this hold? Is it expandable? I'd rather not spend money I don't have to but I need to run some 50-60,000 line programs and it seems that I will need to drip feed these ?? Any insight or experiences would be greatly appreciated as I may purchase one by tomorrow. Thanks in Advance.
