Ramon. I see you're fairly new here. Fill out your user profile and you may get some better help or assistance. Otherwise, you could be taken for someone with other than sincere intentions. I don't suggest that's the case but that's the just simply reality, more information get's you taken more seriously, particularily if you're complaining.
OK, I think my 3130 is underpowered too. Additionally, it's new and has an issue or two for the dealer to address which I'm confident will be resolved. However, I genuinely like mine and have no remorse over the purchase. If someone who is in purchasing mode asks my opinion on the 3130 power, I tell them to move up in power (knowing what I do now) but I don't wring my hands over mine being perhaps a little short there . I can't help but feeling I/we are missing something here???
