Best value for budget boat

Been looking through the this forum for some info but can't seem to find anything for the budget I'm looking in. Looking to buy a boat in the fall or spring in the range of 60k-70k. This will be our family's first wakeboard boat and want to get the best bang for our buck. We do some wakeboarding and kneeboarding but want to learn to surf as well. My local store is a mastercraft dealer so we have looked at the nxt20. Could possibly stretch our budget to the nxt22. We really liked the extra space up front and the width of the 22. My questions is what other options should we explore? Really like the idea of having new with warranty and getting the latest technology but would I be better off buying used? When looking at some entry level boats I like the fact that mastercraft will actually put their name on their entry level boats. Other manufacturers have an entry brands like Malibu (Axis). Any advice would be appreciated.
