My Mio C320 is still kicking but for how much longer I dont know. Since I am not a fan of Garmin or Tom Tom (Igo with Dmika is my choice) I am contemplating going with a cheap Chinese 5 or 6" unit.. I figure at under $80, you cant really go wrong. I am seeing Sirf chipsets which I know work well and now I am seeing mediatek as well - haven't heard of them and there is not much info on them - I see on deal extreme their cold start times are around 300 seconds where the sirf atlas v is around 40 seconds. Does anyone have an opinion on either of them?

thanks
jim
