You can pick up a second hand Garmin 405 or similar on Ebay for around that price. There's usually quite a few on there all the time.
You might be able to get a second hand 205 for even cheaper than that. You don't get a warranty but it's a lot cheaper than buying a new one and some of them have been hardly used.
In my experience Garmins are brilliant when they are working well but prone to breaking down.
