Hi Rog
why not look at a 2nd Hand Ski ?
every now and then ones comes up on Sealine, normally at about half of what they cost new !
I got myself a ski for about R 3000 last year sometime on Sealine, was for a red and white Erics with a paddle.
About the Macski
I also went and looked at the Macski, no matter what anyone says, it's a copy of the Big Tom, and a very very close copy at that.
I have heard good things and I've heard bad things about them, but such is life, some time some one will be unhappy about a product.
I think they go for about R 5500 - 6000 new at the moment.
But the cost doesn't stop there, you still need a PFD (personal flotation device), some basic safety equipment, a paddle and then roofracks of some sort to transport it.
A trolley also makes it alot easier, but they tend to be very expensive. Check the internet for instructions to make your own trolley.
And NO, mine is not for sale and NO I've not even had it in the water yet, too many Great White Sharks in PE at the moment.
