Don't know if they're particularly cheap, or any good for bikes even, but I've seen people asking, so... http://makeashorterlink.com/?N13722EE7 Si
I use one similar to this based on a DELL Axim PDA running software called tomtom Navigator www.tomtom.com You can get speed camera warnings FOC as well see www.pocketgps.co.uk Plays MP3's, tells you where to go (Navigation) e.t.c e.t.c Superb piece of kit. RO
A mate at work has a very similar looking setup - an iPaq with a TomTom 2 Navigator GPS system. It's absolutely brilliant; works really well and considering it's a full feature PDA as well as a very capable sat nav system it was a bargain. So if the GPS on this one is any good, that looks to be even more of a bargain. Especially in comparison with what car-makers will charge to have something similar installed. Mike

I got a Palm Tungsten T new for £160, a neat Fortuna Clip-on BlueTooth GPS unit for £150, and GPSpilot Tracker software for £20. GPSpilot do a route planning app with voice nav for the same money too. It works really well,the Palm and GPS unit have much better battery life than pocket pc for walks in the hills once you are off the bike. The GPS unit uses a new data format called Xtrac which gives you a fix even under tree cover too. I was a bit sceptical about this but it really does work. Also it uses a standard nokia phone battery which are pretty cheap for clones, so for longer backpacking trips where you can't recharge, it's viable to take a couple of spares.
