I have a set of older motorola t5100's (i believe thats the model) they are ok BUT i borrowed a friends set of midland gxt-450's. Boy is there a difference!
I just wanted to see what the range difference really was and i can tell you alot.
I am planning to buy a set before the fall. they are a little more than the cheapys but hey if you keep them for years they will be worth the extra$$.
Buy .com
Here is where i have found the best prices on them.
And hey i just noticed midland is making a gxt-500 ,i must check it out!
