Anyhow, on hobbyking they had (now is in backorder, and who knows when and if will be back available): http://www.hobbyking.com/hobbyking/s...dproduct=26588
... that is a ALL IN ONE PRO clone + GPS ... for just 62$ + shipping (3$) ... so the best possible price.
As cheap alternative solution there is this path:
(26$) .... but it need some hacking (or i2c) for have a direct connected GPS ...
I'm currently hacking MultiWii 2.1 for have direct access to GPS (no i2c board) ... with a similar board as above ... (a clone of this: http://rctimer.com/index.php?gOo=goo...1&productname=
) ... the drawback is that GUI and GPS can't be connected on the same time .. but for the rest ... all is looking good so far.
This means that for 50$ you get all the needed parts ... for have a GPS controller ...
I have been following the new HK board thread and there is some debate as to whether the resolutiuon of the barometer is as good as AIOP. The HK board only supports Multiwii
