I was talking to someone today (he will probably chime in here at some point) who said he uses his GQ-4x4 to check TTL IC's and RAM. I have no idea how he does this. Is there a website somewhere that explains how? I should have asked this before buying my other tools but I am now curious. Can the GQ-4x4 replace these:

subscribed. Would be nice to know. I have one of the first devices that you posted and it gives me a lot of false positives and negative. So much to the point that I dont trust it and use my old parallel device from the 80's.
 
Seconding the Chinese IC tester. It works fine with some, others it's not reliable.
 
I said screw it and bought a Wellon VP-190 this morning. Not sure it will do everything I need but I got a good deal on it so I couldn't resist.
