Downsides to salt pools

[nater]

My experience:

Experience with pool prior to SWC: 18 months
Time with SWC: 12 months
Salt Level: 3200 ppm
FC levels (Ave): 4-6
pH levels: 7.2-7.6
TA (Ave) 120 through late this summer, now at 80 to reduce pH rise
CH: 300
CYA: 120 to current level of 70
Temp range: Winter 40-50 deg, summer 78-86 deg
Pool type: Vinyl Inground
Metal Elements: Stainless Ladder in deep end, light ring in deep end, handle on skimmer lid, plates is SWC cell. (No Heater, no copper, etc).

Observations:
After reading the threads about possible corrosion due to SWC operation, I took a very good look at my pool and equipment.
-I see absolutely no staining or degredation of the concrete at the pool exit points.
-I see some corrosion of my light ring. This was a pre-existing condition and most likely due to low pH (<6.8) resulting from puck usage during the off season (and before finding this forum ). It has not increased during the year of SWC operation.
-I rigged a kitchen cabinet pull handle to my skimmer lid for easier removal. The screws inderneath the lid have corroded badly. They are NOT stainless. This is not unexpected as I usually add salt to the skimmer when needed. No surprises here.

I believe that prior to purchasing such a system, the buyer owes it to themselves to do a lot of homework. Ignorance is no excuse, and unfourtunately the majority of people in this industry seem to have an aboundance of it. (Anybody that's been "Pool Stored" knows of what I speak)

A SWC system is not a magic bullet. As with any other technology in any other industry, education and awareness of the system's pros and cons are required to make a good descision. For me, it is an absolute perfect fit. For others it may not be the best solution. This is where the "Industry" fails and salt chlorinators in general get blamed for problems resulting in poor execution.

I hope Waste chimes in on this subject. He's got loads of experience with various setups and I'm interested to know his thoughts.
