I try to put people ahead of electronics.
It used to be that computer systems cost thousands of dollars. Now they are expendable making repairing those systems less likely as the cost of repairs can in most cases equal or exceed the value of the system.
I'll consider your situation, and make the best decision that will get you the most for your money. Sometimes repairing an aging system doesn't make much sense, so I'll help you chose a new one that suits your needs the most.
