Hi,
I was in the same boat until recently. I wanted a decent, rugged GPS for my bike but could not really afford a newer offering.
I watched the Garmin listings on ebay for weeks and every time I saw something affordable, I went to the Garmin site ( usually the discontinued section) and read up on the specs.
It did not take long to figure out that the Streetpilot III offered all that I needed at the price I could afford.
It had a colour screen ( a BIG one), voice navigation, auto routing and all the other features that I thought I should need. Just as important, the price seemed right. They seemed to be going for around £60 to £75 although some bidders got carried away and I saw a few go for up to £100. (Silly really!).
Ideally, I would have liked one of the 26XX series but they went for a little bit more than I wanted to pay.
Eventually , I got one in good condition, boxed with all the proper paperwork, cables, card reader, 128MB card, unlock codes etc etc and with City Navigator Europe v5 plus the v6 and v7 upgrades. I got it for £65 including postage and had it delivered and up and running within a couple of days.
First impressions is that it is a well built , rugged piece of kit. It's REALLY BIG and a bit on the heavy side (especially with the six AA batteries installed) However, it really does a great job once you master the push button interface and sub menus.
Loading the maps is a piece of cake once the data card reader is installed and I managed to get all of UK and Ireland detailed maps on a 128MB card. I later binned the Ireland maps because I needed some space for routes and tracks. I'm searching ebay for an extra card so I can load the France maps I will need in the spring ( I don't want to overwrite the UK maps but I could if I only had one card)
Bottom line... A fine piece of kit for sixty odd quid and it works a treat with a very good display and pleasant voice prompt. OK, some of the maps may not be totally up to date but , for me, a GPS is only a guide to where I'm at and which direction I'm heading. If the little arrow appears to be travelling across a field on a parallel track to the road I'm on, I'm aware enough to figure out that someone constructed a new by-pass road at some point. I'm not going start crying over that and I'm not going to pay £400 just so the little arrow is always right!
Before I loaded the maps, I downloaded Mapsource World map and free upgrade. Then I installed the City Navigator maps (unlock codes needed). So, now I got really detailed maps of most of Europe and passable maps for the rest of the world. If I need more, I can always get the Wandelust maps which I hear are Quite good.
I'm not even going to discuss the down side of the Streetpilot ( Heavy, slowish rerouting, limited memory for maps etc. etc.) because, for Sixty five quid, who gives a sh*t!

A word of warning to anyone buying a GPS or mapping software on eBay... make sure that it comes with all documentation and UNLOCK CODES! I've seen a few 'bargains' that I would not touch with a bargepole for one reason or another.

Also, be sure you know what you are buying. The earlier Streetpilot GPS,I, II, V etc. have less features and are worth a lot less. Log onto the Garmin site and find the discontinued models and you will see what I mean.
I saw a bloke bid over £90 for an old Street pilot with a mono screen, no voice, no unlock codes and only a car charger ( obviously nicked).. Will he be dissapointed?
All I have to do now is find a decent Bike mount. Being a canny Scot, the Touratech and other expensive models are out of the question but from what I have seen of the RAM mounts, I may go for that option. They seldom appear on ebay so I will probably buy new... they appear to be very reasonably priced.

Yep! The Streetpilot III is a very good second hand buy for between £60 and £75 depending on 'extras' included. You should not pay much more!

Regards to all.
