IR3300 stapling

[bnmand]

I am interested in upgrading an IR3300 so that it can staple. I understand this can be done one of two ways:
1. Finisher J1 or
2. Inner2Way Tray-A1 with Saddle Finisher-G1

I've been looking on the net and can't seem to find these anywhere in Australia. If I purchase one of these, I'd purchase from Australia as I imagine international shipping costs would be prohibitive for bulky items such as these? Correct me if I'm wrong.

I was wondering:
1. How much these cost (so I can determine whether the benefit justifies the cost)
2. Which option is better for performance, ease of maintenance and low maintenance.
3. Which option you recommend.
4. Do I just need to connect to the copier using IEEE1284 parallel cable and use SST to update the firmware so the accessory can be used? Is the firmware included in the System part of firmware?

I'm after accessories in good working condition.

1)you can get the j1 finisher at almost nothing from singapore used market.I could send you one if could take care of the shipping cost .
2&3)I have the j1 finisher only problem i found is it can staple only at one end the carriage cant move around when you need to do a double staple on the edges .
4)No firmware upgrade required for J1.
