Horses for courses!
There are a great variety of handhelds you can buy and I have tried the Delcom and Icom variety.
I currently have the A22E with the VOR facility.
Would not buy the VOR facility again and I would if you can buy one with just the AA battery pack rather than the NiCad pack. The NiCad will die after about 3 years. If you use it regularly you may extend that period a bit. For back up purposes best to have some fresh AA batteries in your flying bag.
Not the cheapest but certainly the most reliable option.
FWIW
