USB2BT vs Nulaxy USB Bluetooth Adaptor vs Teensy 2.0 + Bluetooth module

So, I've been wanting to try a new project.  Lately, I've been wanting to try and make a 60% Bluetooth board so that I could take it with me.  I've got a couple of questions on that front as such.

First, is there an advantage to going the Teensy+bluetooth controller route that I'm not aware?  I'm largely incompetent when it comes to coding and creating a matrix, so the Teensy+Bluetooth module is probably the more difficult for me even though I have a Teensy 2.0 already.  If it's a better option, it is something I could try.

Second, has anyone tried the Nulaxy USB Bluetooth adaptor?  I've been looking for a teardown since it appears that it could just be aUSB2BT adaptor in a fancy package with batteries.  If that's the case, it really doesn't make sense to buy the USB2BT when I could easily cannibalize the Nulaxy.

Lastly, are there any other options out there?  I know about Hasu's controller for the HHKB, but I have a few Alps PCBs and plates that I want to play with.



And, not completely related, but cool, Bluetooth Model M I saw on Youtube.  Maybe it belongs to someone in here.

I used a Handheld Scientific bluetooth adapter for my bluetooth atreus build, if you use one of those, I have some build notes on github.  I paid about $35 for it, and it was easy to work with.  It doesn't seem like there are any way easier/cheaper options.
