i have a 2000 system, its a great and dependable and easy to operate but we've outgrown it and wished we purchased the 5000 system off the bat. Part of the reason is that the staple heads need to be replaced about every 50,000 hits... which for us is every 2 months (@$200 a piece) and is a little underpowered when finishing 38 pgers. If you can get a second tower do it, hand marrying 14 sheets plus the bins can be tedious and time consuming.
