Cheapest way to get faster frame rates for smooth slow-mo?

I want a HVX200 in the worst way but it may be out of the question (school is expensive). I want to push my video's further, and as with all action sports, the coolest thing to see is smooth slow motion. What would be the cheapest or most practical way to do it?

I've been shooting 16mm but it's getting too expensive.

Check out specs on the upcoming Sony V1U. It is suppose to have a super slow motion mode, capturing short bursts of slow motion.

I checked out an HC3, but I would rather not go HD if I don't have to. Plus, 60fps would be enough. Does anybody know de-interlacing 60i work?

Just rent an HVX for the scenes in which 60P is required.

Checked into that. No rental houses near here and I can't find one that will ship.

Possibly, this:

It's pretty cool. Requires patience (so does any good result). Good luck.

With what I've seen and done myself, the After Effects method produces identical slow-motion as Cole's method. That's an alternative for the PC user if they don't have a mac.

Benjamin already posted the link but here it is again for those who missed it:

It's great, fast and easy and works just as well as Cole's method for those who don't have a Mac.

I'd like to get Twixtor but it's so expensive, but the demo they have on their website is simply awesome! The amount they slow it down to while retaining crisp, smooth motion and picture clarity is amazing. It's definately on my to buy list.

The workflow what Cole describes is pretty much what Adobe Premiere does natively when slowing down 50%. In other words if footage is interlaced then premiere slows via repeating fields by frame. If it comes more than 50% then premiere repeats frames.

I'm surprised an NLE would use this method as you are throwing away 50% of the resolution.

All the more reason to step up to HD!!!

Record 60i in HD and each field has enough info for a full frame of slow mo. By upping your rez in camera quality, you don't have to sacrifice spatial for temporal freedom.
