Yeah definitely try it out if you have some basic wrench knowledge....autozone sells remanufactured axles for like 130, and you could probably get them for about 60 or so with a core charge. I've heard quite a mixed bag about autozone's reman.'d axles though...some have had the best of luck with them, some have gone through over 10 and still have yet to find one that doesn't vibrate. Luck of the draw I guess.
It's really not a difficult process at all, just need the axle nut, your typical array of 12mm-17mm sockets, and some extra cotter pins (just in case the stock ones break) and a nice long good and sturdy breaker bar. I'm going to be replacing my front left axle pretty soon here, as I've been riding on a deeply torn boot for about 4 months now. No clicking yet, so I want to get at it as soon as possible.
Good luck.
