After that you are getting into some serious money and definitely going to be harder on the engine.

They are using budget as a verb which means the amount you are willing to spend. Not as an adjective which means inexpensive. Everybody's budget(amount they are willing to spend) is different. For some it is $1,500 while others may be $15,000. Hence the reason for the different budget amounts.
