I've tried a few, the 60 CSX was the best as far as functionality but I found for the bike ( 530 Rally) and the tyype of riding we do, it just wasnt right. The antenna on the 60 CSX fouls on the brake line ( you cant change the orientation on screen) and damages the antenna, the colour screen I found great at most times, but when I was a little sand blind I struggled to see the track. Here we almost all use ( those who venture dep into the desert) the Garmin V. Its old, doesnt have much memory but its strong. The V last through all the harsh conditions, heat ( up to 50 Degrees Celcius), dust and constant bashing. The orientation ( that can be changed) is great, the B&W screen is visible at all the times and with the Touratch mount the antenna is will hidden away. The really only limiting thing I have found on the V is the memory, when we do our big 2 or 3 day rides with many wayoints it wont hold them all and we need to do a little data entry on one night. For a basic as you can get GPS that keeps mazon) its a great choice.
