Acquisition speed mostly depends on the chipset used in the device, the antenna size and the surroundings (open space vs. inside a building). In any case, a cold start of several minutes sounds like *a lot*. Modern devices are able to start in less than a minute: http://wiki.openstreetmap.org/wiki/GPS_Chipset#Vendors

What do you intend to use the GPS for? Photo geotagging?

I want to build a little bread crumb and position marking unit for geomarketing, something that looks less like a consumer item - our company had instances where people where badly assaulted and the Juno units stolen. If the unit just looks like simple box (nothing you will see or have seen in shops) the probability of it being stolen is less. For data quality we also need to check that the fieldworker actually covered a certain geographical area to obtain all the data required and didn't just stand in one spot for an hour and collected some data and thumbsucked the rest.

Nah the spotmeter thing I left, and as for photo tagging I'm not really that interested, I use my Garmin to mark points of interest for photography at a later stage.

Thanks for the info Dimko.
