I personally like this one, I've used it for about a week, i broke one thing on it(i think it was defective one of the collars got cracked) but other wise its very nice, and amazon has already issued me a return label for it. i actually just broke it this morning, and if you have amazon prime, you get free 2 day shipping, right now it is priced at $53.99 for the 937+ which is reasonable for what i tis, you can also look at the 937 or even the 936 if you need to save money, here are the links to all
937+

937 amazon doesn't seem to carry this one
936

ultimately i think the problem i had with mine was a manufacturing defect and not a problem with all of them, as the reviews of it seems good
