Researching the ASIC market

Hi Bitcoin talk forum

I'm new to bitcoin mining ("new" - not actually started yet), and I'm trying to get my head around the current ASIC miners out there, but with hundreds of topics with hundreds of replys in them, it's really hard to wrap my head around whats going on.

I was interested in buying some USB ASIC miners, but I haven't had any luck figuring out where, how or for how much to buy them. I've been looking at the Block Erupters and the blue fury.
When looking for a place to buy the Blue Furys I stumbled upon (impossible not to as it is the top google result when searching for "Blue Fury") the website "asic-technologies.com". But I also read somewhere that this website is a scam, and after a bit of back and forth with their support (clearing out questions - not asking if they are a scam) I don't have a very good feeling about them.

But other than that It has been difficult to figure out what the current prices would be for a few Blue Fury miners and where to buy them other than there has been a few threads about buying them on this forum (which are some of those confusing threads I was talking about).

Also, I read somewhere that one could buy a bunch of Block Erupters with a usb rig and everything included for the same price of a few Blue Fury miners (resulting in the same hashing power).

Can some one help me? what is the current situation on the USB ASIC miner market? Where can I buy Blue Fury miner or a bunch of Block Erupters?

Ps. It might be worth mentioning I live in Denmark? Regarding where or from whom I can buy...
