Hi Ken,
I use a Garmin Etrex Venture, which i have been using for the past 6 months, it has served me very well so far. I even got accuracy of 4ft on a foggy day on Ilkley moor. I am happy with that. I bought my one on ebay, it was only 2 weeks old at the time, got it for 60 quid, it was 150 online. So shop around, check ebay.
