I try to stick to ACDelco whenever possible, at least for all electrical items, you could go for another brand, save some money, and still get a quality hub.
Timken makes a good hub/bearing, I like you had money issue when I replaced my driver side hub, so I only replaced one side, normally I'd do both, but if money is tight you'll be ok replacing the one that is going bad, just replace the other when you can afford to.
Really the AC Delco hub is only a few dollars more than the Timken, either are quality hubs though.
ACDELCO FW293 $91.79
TIMKEN 513179 $86.79
Prices are for RockAuto
Even better for the ACDelco if you happen to have Amazon Prime, if not in the end after shipping it should still be cheaper.
Changing the hub is not to hard really, depending on how rusted the splines are, my drive shaft, and hub were severely rusted, I sprayed PB Blaster Heavy Duty Penetrating Solvent into the area and let it set a while, then resprayed, let it set a while longer, then sprayed it one more time and started banging.
I had a 5lb mallet and I had to whack the hell out of it to remove it, I was going to get a slide hammer, but I don't think it would have worked that well considering the rust.
I highly suggest ordering a new spindle nut to use once you are done, that way you can take the old one and thread it on so the top of it is flush with the top of the drive shaft, that way when you go to hit the drive shaft the nut will help protect it, that way you do not damage the shaft.
Hopefully what I am saying makes sense, if not I can try to find a video..
Here is the part number for the spindle nut. DORMAN 615144
When putting the new one on I would use some anti seize on the hub/spindles, also a little on the hub bolts.
