If that's the SKF one, then it's about right. They do one for about half that, which is what I used.
As for doing it, the hard part is removing the hub from the bearing, for which I made a puller. That was after struggling for a couple of hours with packers, bolts and swearing.
The circlip is the next fun part, you need some hefty pliers to start it moving, and I find that working around the edge with a couple of screwdrivers is the only way to get the damn thing out.
Actually removing the bearing is easily accomplished with the same tools you would use for a FWD bearing. Or you could use some studding and spacing plates.
If you put the new bearing in the freezer overnight it's easy to fit, or you could use the same tool that removed the old one.
Pulling the hub back through the new bearing is much easier if you have an impact wrench.
You will need a decent jack to get the car as high as you can, and of course axlestands. The hub nut is about 300Nm, so undoing it could be interesting.
This isn't a difficult job, but you do need equipment that isn't in most toolkits.
