At $100 the SkyScanner is one of the better choices, and still somewhat compact (only you can judge if it'll be okey, I hope the links helped :-) ).

Many of the telescopes in this price range are garbage, and the ones that are OK have some compromises. A shaky mount, bad accessories or even bad optics result in frustration and beginners quitting the hobby before they really got started.

Sadly the Celestron c90 got much more expensive last year, else it would be my budget travel recommendation. Now it costs as much as a better telescope.

Still, for $100 are a few other possibilities, but most aren't compact. Something like the SkyScout 80mm could be another possibility - I have not used it myself, and I am not a big fan of short achromatic refractors. Such short refractors have some issues (chromatic aberration reducing the contrast at high magnification, so not ideal for planets), but for $100 it could be something that'll suit your needs and comes with a usable tripod.

In the $200 price range a few other solutions pop up. A small 3.5"-4" Maksutov for example, which is a very short type of telescope, it'll work on a compact camera tripod.

And of course the 5" AWB Onesky - it's my favorite telescope (still somewhat portable, but already shows a lot). It costs $200 but it's less of a compromise regarding what it'll show.

While it's a struggle to spot some details in a 3" or even 4", the 5" already shows quite a bit. I have a similar telescope to the Funscope (a noname 76/300 table top) and the planets where underwhelming. The 90 and 100mm Maks where much better, but in the 5" everything is just more impressive.

Telescopes are more rigid than you might think. The thick glass of a mirror is actually pretty durable ;-)

It all boils down to budget, size and what you want to observe; Here are a few examples on what to expect visually-> Links.

For planets, the SkyScanner 100 or other shorties would need another eyepiece, e.g. a decent one such as the 3.2mm HR Planetary (from $33) - cheaper ones or the ones in eyepiece-sets usually have a very short eye relief and are garbage. A budget solution is combining the kit eyepieces with a 3x Barlow for ~$15, but along with the rather basic kit eyepieces and added chromatic aberration of such a barlow, the contrast decreases.

There are a few good used deals on CL; but nothing meeting the size requirements at the moment, sorry :-)

.

Binoculars are of course a great tool and great for traveling and wide-field - though won't show planets well (besides the Galilean moons and Venus phase) due to the lack of magnification. Even some cheaper ones are a great addition to a telescope, and make locating targets easier. 1 2.
