Especially considering the price range OP has laid out: from 2.1k to 7k.
There are others at these price point but these are the one I could find where there are favorable reviews on the web.
Right. I understand that. If you don't have brick & mortar availability, you have to start somewhere. That's what I did, but now I may be suffering a bit of buyer's remorse. What will you be driving them with? That would at least give you an idea if you would be locked into certain specs.
