76mm or 3inches is quite small for a reflecting telescope but it is about the lowest price or something useful astronomically.  There is a similar sized reflector in the Celestron range and that has the advantage of an equatorial mount although that can be a bit of a mixed blessing unless you can in effect rotate the eyepiece position around the axis of the telescope to keep it on a comfortable observing position. I am reasonably sure that its performance will be to specification but this might be a bit disappointing if you are expecting to see as mucg=h as in recent quality pictures.

A 76mm reflector should produce slightly better results than Galileo's telescope ...

Quote
The Galileoscope is a small (2 inch), mass-produced refractor telescope, designed with the intention of increasing public interest in astronomy and science. It was developed for the International Year of Astronomy 2009.

It is meant to be an inexpensive means by which millions of people can view the same things seen by Galileo Galilei, such as the craters of Earth's Moon, four of Jupiter's moons*, and the Pleiades.

[*Jupiter's moons just appear as points of light, like stars]


You should just be able to make out that Saturn has handles rings ...

3" or so is good for a refactor, I think.
It is somewhat on the small size for a reflector.  There are many 4" and 8" telescopes available, some relatively cheap.  Perhaps you could pick up a bit larger telescope on Craigslist (or the local equivalent).

One of the things you might consider.  There are several telescopes available with automatic star finders.  It might come in handy.
