I ask that because I can tell you don't use the computer for income......
you're looking for a deal - as a small architectural company - I make @ $1000 / day with my apple computers -
I buy whatever I need.....and don't question the cost - because every minute I'm not working - (instead of looking for a deal) - I'm not making money.
but I hope the best for you........just remember that the computer is just a tool - and it's not as much about the hardware as much as the user....
