This machine has now been discontinued, however there are a number of cost effective alternatives that you may wish to consider.
If you would like to consider a highly cost effective and completely automatic wire closer then perhaps the AWB-320 would fit the bill.
Other available devices are the highly robust and easy to use manual options, such as the Rhinotuff HD8000 and the GBC MC12 wire closers
