Current Best USB Miner on Market

[Proteus123]

Where would I go about buying it and at what speeds? Can't seem to find anything over 2.5 GHS, is that the limit?

If you're talking about purely USB (no external power), and I think you are, see my StickMiners thread.  There's several over 2.5GH/s.
I won't make any purchasing recommendations, for reasons also outlined in that thread   The tl;dr on that is that they're all too slow, too expensive, and certainly will 'never' ROI.

Yeah I'm aware of the terrible (read nonexistant) time to ROI, thanks for answering my question

.. the New Rbox.. not really a "usb" but it sort of is.

I've been contemplating a 'pod miner' thread, but it's kind of difficult to come up with criteria that would give a clear separation between those (r-box, antminer u3, HEX16A4, Gridseed official-name-escapes-me) and, say, a BlockErupter Cube, BFL Jalapeno (still 'desktop' miners), and ultimately the 'bigger' miners that could be used on a desktop, but probably should go in a datacenter, without incidentally excluding a miner that should be part of it.  But yes, if external power is an option, then there's quite a few more options that are very desktop-friendly.

I'd consider a "desktop miner" as something that could run off a DC brick. Likely a USB cord, possibly its own ethernet connection, but if it requires enough power that an ATX or something is required it's past the cutoff for me.

If you are talking about a pure USB miner bitmain is probably your best bet. Rockminers are usb as well but require external power sources

Yeah, but then you get into discussion of what still qualifies as a DC brick.  Does a laptop adapter count?  You can get those well above 100W nowadays.  I've even seen some 200W ones advertised for 'gaming laptops' - can't say I know if that's proper output or just throwing numbers around there, though
USB vs ethernet is a slightly simpler criteria, in that it probably shouldn't be one.. once things are externally powered, those are both relegated to just communication anyway.

They're solid little miners for sure.  I'd go with the U1 myself - slightly less heat management needed and no ungainly heatsink on it - practically a copy/paste of the block erupter USB.  Though given none of them will ROI and it's intended just for fun.. any choice will do, really.

the new rockminer r box is a good usb miner it requires a external power source though

USB miner is the worst, please dont buy them.

Reason: They have the most expensive price/GHS and they have the highest watt/GHS.
