Repair fork or get new one? Right now, I have a pretty old and terrible fork: 2006 Manitou Axel Elite 100. It's leaking oil like crazy, and I've almost eaten it a few times because of how easy it is to bottom out the forks. I pretty much have to ride with lockout on.

So my question is what would it take to repair them so that they are usable? Would it even be worth it?

If I just need to get a new fork, what should I get? I haven't needed to upgrade anything for a while, so I'm out of date on everything. I really don't want to spend more than $150, but I'm fine buying used. Is there something besides Ebay I should look?
If your time isn't worth much and you like to tinker (like me), at least take your current fork apart and see if there's anything you could do to improve it's situation.

That said, based on your description of it's problems, I think you should buy a new one. And I actually mean new, in this case. Normally it's better to buy a used bike than a new one, but with something that's as age-sensitive as a suspension fork, I'd buy a new one (and take care of it, maybe get a stanchion boot).

As to what fork you should get... take note of the specs of your current fork (brake options, wheel size, stanchion size, travel) and get something similar. $150 will get you something decent.

If you decide to get something new, Amazon, Ebay, and your LBS are good places to look.
