Nick - Lots of members of this forum make neo blades, including myself (for my own use) and many sell them (just watched Space Winduís awesome string blade video last night!)
That said, I recommend that before you totally discount building yourself, watch the videos out there...TCSS/Madcow has a great one, Tom Tillman has a great one as well...itís not childís play, but also not all that tough with some basic tools, research and prep/planning. You can make your own for maybe 70 bucks and pay upwards of 150 to purchase a (likely weíll made and sturdy) blade.
All of this said, if you have no interest in the build part, you have made your request at the right place...if I were looking to do so, I would buy from many of the elite sabersmiths and installers here...no shame, just encourage folks, if they are predisposed, to give it a go because I have so much fun since I started. Best of luck either way!
