'87 535i Clutch Problem

[Hypnotised]

Starting about a month or so ago, when I would go to my '87 535i after it sat all night, the clutch would have slipped down about halfway overnight. Hydraulic? All I had to do was put my foot behind it and pull it back up, and it was back in place and fine. Now it's gotten to the point where while I'm driving around town, about every 15th or 20th time I push the clutch in, it will not come back up all the way. However, if I put my foot behind the pedal and pull it back up, it stays in place. Now something is obviously wrong, but I'm just not exactly sure what to replace. I've been told several different things. I've been told it's probably the clutch disc and the pressure plate. I've also been told it's probably just the clutch slave cylinder. I've priced the entire clutch kit (cheapest brand OEM $274.00. It may be a LuK. Also an AutoCom brand for $221.00.), and a slave cylinder for about $50.00.
I am not a wealthy man, so do you think it may be possible to just replace a few select parts (i.e. clutch kit and pressure plate) only, and not have to do the clutch master cylinder, also? I have a mechanic who will do all the labor for about $300.00. GREAT DEAL! It still comes out to be around $600.00 total, no matter how you look at it.
Based on what I have described it is doing, what do you all think might be the crux of the problem here.
Thank you.

^ please know your information and what your talking about BEFORE advising people on what to do.... Specially on such a big job such as a clutch.... Thanks

Around $220 isn't bad for a clutch... But you don't need one from your description

It sounds like you need to replace The Clutch Slave Cylinder and Clutch Master Cylinder Replace the line too because it is probably going to go soon to! It Sounds VERY much like your hydrolic fluid is eather leaking out of the slave Cylinder or leaking passed the seal in the Clutch Master Cylinder up to the resevoir or out into the cabin(by you pedals)

Ok, I just read it again Change your Clutch Master Cylinder(Not to be confused with the brake!) Then the slave Cylinder
Check is the slave cylinder is leaking ALSO BEFORE ANYTHING Check your brake fluid level is it low?(Clutch uses the same resevior) does it keep going down? if so see where it is leaking out (check by the clutch pedal) and under the car If it isn't leaking in the car(Check CAREFULLY for dampness and check behind the carpet!) then change the Slave cylinder first!
