I have a '98 Boxster and the driver's side window doesn't drop enough anymore when I open the door.  I do hear the motor when I pull the handle.  I tried the zip tie trick to tension the wire, but it didn't solve the issue.  So I believe I need a new window regulator.  I've read a lot of threads here and I believe the general belief is that the various OEM options are hit or miss.  They often visually look different (so perhaps not OEM).  I'm hoping this is a quick project (e.g. mark where the existing window regulator is to minimize and/or avoid having to adjust the new one).  My question is...
- Should I simply purchase a genuine Porsche window regulator for around $300'ish
- Buy a used from a dismantler for around $90
- Other options?
