Yes, a taller tripod is an easy solution, and they don't need to cost much. A heavier tripod will tend to be steadier than a light one though, if you don't need to carry it around, and better quality ones may offer better pan and tilt, and stay put better. I bought one from a camera store, which has done double duty under a camera.
The great beauty of an angled eyepiece scope though is that you can set it up right next to your shooting position, such that you only need to turn your head slightly (without changing any aspect of your shooting position) to spot your shots. For the range I prefer this type, though a straight one is perhaps just a bit easier to get on target in the field.
