wakeskiing doesn't look terribly fun to me... as the skis right now are terribly bulky and obtrusive *might change in the future though*.. I would recommend wakeskating as a cheap way to have fun on the water... especially since it doesnt require any type of large boat to have fun... jet ski/jon boats are perfect for wakeskating, as there is alot more tricks you can throw in the flats, i/o, and even just sliding the lip wabahhh wa bahhbahh
I know I didn't answer your question.. just trying to help lol... also, you can get a decent used wakeskate for ~100 bucks if you look hard enough
