I have a meade 4.5" reflecting telescope, but images are seen upside down.

An erector prism. Usually it is not an eyepiece, but rather an addition extension that you put your eyepiece into.

If you are only looking at celestial bodies, and not Earth based things, then the only conveincience having the image right side up will provide is it may make it easier for you to manually control the scope.
If you plan on using it a lot, you will quickly get used to having things upside down though. Remember, in space, there is no right side up or upside down.

Is this what you're looking for? http://www.amazon.com/gp/product/B0001DZ33U/102-0848766-0027331?v=glance&n=502394
[edit]
Thought I might add that I've always heard of these accessories referred to as "image erectors," never "eyepieces" of any sort. It's no more an eyepiece than is a filter or barlow lens.

It's called an erecting eyepiece. If your reflector is a Cassegrain type (eyepiece at the back) you're better off using an erecting diagonal, but if you have Newtonian, this is what you need.

I believe it is called an objective lens.
