I am using LEDstrips I bought from Ebay for over a year and they still work fine. I am sure there is a quality difference between different brands. Depening where you use them and how important they are you could choose a matching quality.

Quick and good communication.
BTW it's not so nice to ask if a forum is "dead". It might be you are asking about something that has been discussed many times before and may be you should get a little more 'active' and do some proper searches. There are plenty of threads with info about the same subject.
