I've bought a couple of bins at Captain's Nautical Supply. Not super
cheap, but they'll let you walk out into the parking lot and look at
starlings sitting on telephone poles, which is a great test if any are
around.

Anacortes Telescope is also very accommodating, and cheaper of course,
since it's really a mail-order shop.

I recently bought a Leopold Yosemite 6x30 porro for my daughter. I
really like them. Very light for their size, small enough for almost
any kid to hold after maybe 1st grade, nice contrasty image, pretty
well baffled, wide field of view WITHOUT VERY MUCH DISTORTION until
quite near the edge, huge range of interpupillary distance, twist-up
eyecups, long eye relief, available in several colors of rubber armor,
nominally waterproof, under $100 mail-order. The claimed close focus
distance is a bit long (16' IIRC) but it appears to me that the real
close focus is more like 9 or 10 feet; probably an effect of the huge
depth of field, which along with the minimal jiggling of the image and
largish exit pupil is an advantage of the low power. We were looking
at the Pleiades recently, and they brought out enough fainter stars
and also had a wide enough FOV that she could see that it was a big
roundish star cluster. We've been using them as opera glasses as well
at concerts. The focus wheel is a little stiff for kids, but the
large depth of field means you don't have to focus much if you are not
moving constantly from wooded to open areas. For the price, I think
they are a slam-dunk.
