I doubt you'll be able to get the whole drivers side cheap. Even if you could get just the outside shaft, you would still need to replace the inner boot. Like I said, rockauto worked well for me. If you have c clip pliers, the job should only take you a few hours at the most from jacking up the car to getting it on the ground again.
Procedure from start to finish:
1) jack up front of car and remove driver's side wheel
2) take cotter pin out from castle nut
3) put wheel back on and lower car
4) using 32 mm socket and big ass breaker bar, break axle nut loose
5) jack up car and remove wheel
6) back castle nut out enough so that it comes off the axle by a few threads
7) locate BFH and give the top of the castle nut a solid punch to break the axle free of the knuckle (I used a sledge hammer like a pendulum)
8) unbolt knuckle from strut and remove wheel nut all the way
9) unbolt the middle axle's carrier bearing (2 14mm nuts)
10) wiggle the knuckle around until you get the axle out
11) cut off old boots
12) clean the old grease out
13) use c clip pliers on the tripod bearing side so you can get the new boots on
14) slide on BOTH the new inner and outer boots as well as both of the smaller band clamps (the bigger ones can go on whenever)
15) repack with gooey new grease (using a grease gun makes this easier)
16) slide new boots onto the cups and tighten the band clamps (depending on the kind of clamps you get, you may need special pliers, i didn't need them)
17) put the axle back in the tranny
18) get the spline side back in the knuckle
19) replace middle axle carrier bolts
20) bolt the knuckle back up to the strut
21) put the wheel on and lower the car
22) get wheel nut back on and torque it down (make sure you can see a hole for the cotter pin to go through)
23) lift car to take wheel off
24) put the cotter pin back in
25) get the wheel back on for the last time and put it on the ground
26) go have a beer, you deserve it
So you see; 26 easy steps, all of which you can do on your own. For those that are interested, I got the Beck/Arnley brand boots from rockauto and they had band clamps that didn't need any special tools. Also, if you are only doing the outside boot, you don't have to take the axle out, but its a lot easier to work with on a bench.
