That depends.
What kind of tournaments do you play now? Do you expect NPPL/PSP quality tournaments? How many other teams are going to be playing X Ball at the same location when you have a tournament?
If you just play local tournaments on existing fields, for the same price, you'll just be able to play X Ball on local fields - meaning you probably won't have an X Ball scoreboard or anything. If you usually play tournaments that cost your 10-man team $1750 to enter, you can probably play X Ball in a manner pretty similar to the way the pro/college teams do.
You're not asking a good question. X Ball can be more, or less, expensive than what you play now, depending on how you play it. 3-man? 5-man? 40 minute games? 60? Scoreboard? No scoreboard? Existing field, one-time-event field? What?
You're acting like all non-X Ball tournaments have one price and all X Ball tournaments have another price, and that's just not even close to true. Some ways to play X Ball are more expensive than what you're playing now, and some are less. Some regular tournaments are more expensive than what you're playing now.
The best answer I can give you is that yes, you can play X Ball without spending more money.
