Which modchipstore do you recommend?

Hi,

I need to buy Blaster 360 for my console, but I have a Hitachidriver and there's problem with older units and mine is about a year, but I'm willing to take a risk since Xecuter will give me a new version of the Blaster when it's ready for delivery.

So what I'm looking for is a online store with good customcare, but I'm not sure which store that is. Anyone here bought a broke modchip etc and got problem with a store, please tell. If you got help, please tell me too. I'm also interested in how the mailrespons was. Is it slow or quick?

Thanks in advance!
