Filabot (or other Filament makers) Experiences?

I was thinking about creating my own Filabot as a fun side project, as well as saving a bunch on Filament.

[www.filabot.com]
[makezine.com]

I figure it would pay for itself within a year or two considering how much I print.

Any experience with it, good or bad? Any reason I shouldn't get something like this? (i.e. future filament tech will most likely be different?)

Thanks so much!
Jeff

Way over priced when you can get a Filastruder for $300.
