No you don't have cash to burn.
Save it. You'll spend it sooner or later. If you really think you have a budget surplus, buy the team pizza. Or just save it for a Saturday during the build season. Also, if you want to take your robot to the next level and don't want to drop a couple thousand on a CNC (and that's before you factor the time and material it takes to set up and use), consider some of the aftermarket robot parts that are popular in first, like my personal favorite,
AndyMark.
6500 isn't that much money especially in this competition, maybe consider going to a second regional? More competitions are great if you can afford the time and the money.
Overall if you got anything to take away from this, wait until kickoff, AND KEEP FUNDRAISING!!!
