Budget?

Ok, I need to limit myself to a budget to buy parts for the spiderbot. Since I am going to piecemeal the robot together I will limit the cost to $800. This is a nice round figure and represents the amount of money that I have saved up for an iPad. Sorry Apple, it looks like I will not be getting one of your got-to-have toys for myself. My wife normally limits me to buying technology with cash because she knows that I will not part with cash unless I really want something bad and I have saved up for a long time. We do have a checking account and various savings accounts and credit cards but I refuse to use them for something like this. By reacting that way, I have been able to maintain a minimum of debt for a long time. Mortgage is paid off by the way so I do have a bit of other cash floating around. So $800 limit it is.
