i have an n800 and i've been hearing everyone here on the forum talk about the hollux models. There's this really cool one from Israel. It boasts 51 channels and its description says bluetooth 2.0 class II
10 meter range using Serial Port Profile



the only thing is that its chipset says MTK and i remember in an older thread, people said MTK was built into the N810 and that it took 3+ mins to get a position fix
