As far as I'm concerned, leasing is a complete rip off.
If you must lease however, here is a price list to add to your notebook.
Office Depot
HP Pavilion 6730 $899
HP M50 monitor $348
HP 612C Printer $148
---
Sub Total: ~$1395
+ tax (assumed in BC)
---
Total = $1590
Estimated prices (from memory)
~$70-80/month for 24 months
$150US back in rebates from HP (if bought before Sept 30)

Hope that helps These are just estimated prices, but it should give you a rough idea. I work there at the moment, but thankfully am quitting on Saturday. I think Futureshop has a better financing program, so you might want to check that out as well.
Beware though, any system you purchase from stores like this will not be nearly as good as ones you could get for similar prices on your own, or even at local mom & pop shops. The systems sold at places like FutureShop and OD are meant for grandma.
