Thanks for that Tomas, very interesting.
I was thinking about getting a XYMT (or whatever they're called) grip for around £50, but I don't think I will now.

I think that's exactly the model no: I bought from Gadget Infinity
But seriously, I don't know it was the reason my 30D croaked for certain.
I have a job this Saturday and I'm tempted to use the 30D with the third party grip with one battery only as I find the vertical shutter release more than helpful but at the same time I don't want it to die in the middle of a job! I use a 1Dmki and the 30D but still, I really do need both operational. hmmm.....
If the only the Canon versions weren't so ridiculously over priced! :razz:
Imagine how much of a chump you would feel if it also killed the 30D, you have likely put a few off buying this particular grip so why risk it again yourself, "hindsight is a great thing".
I personally wouldn't but I can completely understand those who want to.
@Tomas - now you got me thinking. Though I use original Canon Grip, I use 3rd party batteries rated 7.4V 1500mAh.
Why does the word (t-h-o) get starred out? its not rude?

(What Steep said!)
I have YXTM grip on my 400D and 2x 2000mAh Batts - never had a problem.
With all the horror stories though i when i upgrade to a 40D i will get the official grip.
For the price of a new third party grip you can most likely find a second hand Canon grip.
Without being more specific as to what was 'blown' on your PCB it's difficult to say what caused it, if it looked like a supply problem, i.e. current overload blowing a track or similar then I can understand the blame maybe being pointed to the batt grip.
However, the tech behind a battery grip is not rocket science and I'd bet that the internals are not far different between a Canon and 'reputable' third party manufacturer, most of the costing will be saved on the cosmetics/ergonomics and branding at a guess.
Tomas, sure,it may well have been the cause, I was just thinking from both sides!
There's plenty on here who use third party lenses!! I suppose me personally, as I have one on the way, would still prefer original Canon hardware, but if someone could recommend a third party model that seemed good quality I would not disregard it!
