Do whatever it takes but get a Garmin 60CSx!
I got a 60CS in December and it was excellent, better than any previous GPS’r I have had, and I was quite happy with it, although it would lose the signal every now and then if there was any tree cover, unlike my sons PDA with a separate SiRFstar 3 receiver.
When I discovered the CSx in February I had to have one (It’s essential Max, must have latest technology or world will end, etc etc) so ordered one and sold the CS on eBay.
It really is a huge step forward, I can’t believe how sensitive it is, it hasn’t lost Satellite reception once in 20 caches, and on open ground usually has all 12 at good strength, something I have never seen before.
It usually acquires a 3D fix in seconds, and will hold it in my pocket, or even sitting on the stairs of my house, (nowhere near a window), although the accuracy does drop a bit!
The only slight downside is that it does “wander a bit” when you are standing still, which the CS didn’t, apparently my computer and house have moved 300feet in the last ½ an hour.
