Hi there,

can anybody please recommend me a GPS-receiver for Bluetooth, USB
or the serial-port?

There are hundrets of different devices on the market. The chipsets
are: SiRF III, Sony, Atmel and MTK

I've read that SiRF gives the best results right now, but MTK seems
to have a high sensitivity and 32 channels for tracking satellites!

Is there any device under $100, which you could recommend me?

A good model for all around use is the SiRF III Holux GR-213. That comes with a PS/2 connector on the cable, a PS/2 to USB adapter cable, and you can purchase various optional adapter cables to adapt the serial output to DB-9P hardware COM ports and various PDAs.

I have a GR-2313 and it is very fast and has good sensitivity too, impressive for its small size. I also have the SiRF III in my Garmin 76Cx and I never cease to be amazed at the improved performance of the SiRF III chip set over the earlier SiRF II. The SiRF III only displays 12 channels but has 20. The other 8 channels are used in the background.

The 40 channel MTK chip set sounds interesting, I wonder where that is being used.

There is one model of the GR-213 that has only the USB connector hardwired on making it for USB use only, I think you want the more adaptable one that has the PS/S2 connector. Here is an example of it, I have no experience with that seller but they look to be established and reputable:

And here is an example of the GR-213 model I think you do *not* want:

I do not recommend buying from eBay seller "gps4evyone". They are dishonest and cannot be trusted to the follow up on any sales with which there are any problems.
