99% of the time, I am in favor of their bucks, their business.
However, I personally would give pause to signing up for anything beyond a third regular season event (whether three regionals or two and the Championship). At that point, I would take a long, hard look at the current needs and abilities of the team. The big questions would look something like:
- Will the students be able to afford missing two or three more days of class?
- Can the mentors survive three more days surrounded by screaming teenagers without going deaf or insane?
- Can this money help those students who contribute greatly to the team, but can't travel to competitions because of money?
- Is our current level of robot building enough to make a robot that won't leave a mess of parts all over the field from the additional matches and the use and abuse that comes with them?
- Does our team need any additional equipment, for fabrication or otherwise?
- Are we capable of mentoring a rookie/Vex/FLL team?
- Could we use the funds to implement something useful at school or within the community?
If I could honestly answer all those questions and have the signs point to registering for a fourth event, then I'd be in favor of signing up.
