Ok, dusting off the brain cells and pulling out old books, (I'm still utterly distraught that the Passport to World Band Radio is gone!!:tears

, here's what I've got for ya:
First, although we here on the mainland still refer to this as "shortwave radio", it's more currently referred to as world band radio, and is pretty much alive and well over much of the globe, the continuing encroachment of the interwebz notwithstanding. Thus, essentially 100% of these receivers are manufactured and distributed for the rest of the world. And, identical receivers will frequently have a series of several different names and model numbers that are used in different global markets. Also, model numbers change from time to time, and not always in sync with any kind of communication from the manufacturer. Edit: And, frequently you will find out that models have been discontinued, or discontinued here in the US, and there may or may not be a replacement model.
There are five different price/feature categories of world band radios: Professional, desktop, portable, compact portable, and "toys". You're interested in the portable and compact portable categories. One important caveat, if you intend you use this radio for more than "find one station and leave it there", you must have a digital tuning capability. If the radio is analog tuning, don't bother. A keypad entry is certainly a great feature, but the digital tuning and display is a must.
Here are four suggestions for you. I would really suggest you read up on all four, because as you do you'll learn a great deal about what features are important, how the radios compare to each other and to other examples the review writer mentions, and you'll begin to get a feel for the pros and cons between choices. As with every purchase, unless you have deep pockets, there are always compromises and tradeoffs. Again, these are "families" of radios that may be known by or found by different model numbers. Btw, the site danddd mentioned is outstanding!
1. CCRadio-SW; Kaito KA-2100; Redsun RP-2100.
2. Sony ICF-SW7600GR
3. Grundig G5; Eton E5.
4. Kaito KA1102
Once you've made your choice, you can simply google the name to find a source. Amazon usually has links to several models as well. Have fun with this! Winter is coming, and that's the best time of year for listening, and, (fingers crossed!!) we're passing the bottom of this sunspot cycle, so conditions should improve for the next several years.
