Love my '07 VLX, traded up from an '04 Nauti 210. I haven't had any issues with my Illusion tower, so no complaints so far. The boat has been great. There is a 3-year difference in my trade, so there were obvious improvements made to the VLX over that time period. The quality of the BU is great and I like the deep interior more than the shallow Nautiques.
I'd say go for it and don't look back...
