I am looking at replacing both my master and slave cylinder soon as I am about to hit 50k in miles and am running into some shifting issues which seem to be hydraulic related. I have some questions regarding this.

1) Where is the cheapest place to buy a new master and slave cylinder? I see a wide range of prices, so can anybody swerve me to the best price/site to acquire a new master and slave?

2) How difficult is it to replace the slave cylinder as I know the tranny has to be slightly pulled. Any write ups regarding this? How long would it take for 2-3 people that are semi-mechanically inclined in a house garage with jack/jack stands?
