Fuel Injector Rehab

[TooManyAudis at aol.com]

I'm looking to resolve a persistant warm start problem with my 91 200q.  Cold 
starts and hot starts are fine, but a "warm start" -- 15 min to 2 hrs after 
running -- produces a very hard start condition, where I usually have to cycle 
through 3 or 4 attempts at starting before success.

Indications most likely point to leaky fuel injectors, and was considering 
cleaning them (www.injector.com, unless a better source is warranted) or 
replacing them if I can find injectors for significantly less than the $150 or so 
through the various worldpac suppliers.

Has anyone had success with cleaning, or found a much more reasonable source 
for replacement injectors?  Alternately, should I be looking elsewhere to 
resolve the hard warm start issue?  

I figure at 217k miles, the injectors have earned a rehab at the very least.

Thanks,
