Paul,
I am no more then a novice with these radios. Like you, my needs were similar, and about 3 months ago I read what I could on the web and made my choice. At the $200 pricepoint as an upper limit, there are a lot of good radios on the market. In general, you get what you pay for as long as you stick with good name manufacturers.
The Sangean ATS-909 radio offered a little "more" then the Sony ICF-SW7600GR. Personally, at the same pricepoints, I found better value in both the Sony and Sangean models mentioned compared to the Grundig. This is based on my personal research with no
hands on personal testing. My radio at the retail pricepoint was over $200 so, when I found one on Ebay that I was comfortable buying, I struck gold. The Sony was available for ~$150 NIB plus shipping compared to my "used" Sangean for ~$10 more.
I found the entry level for me was something along the lines of a
Sangean ATS-505 but, its pricepoint was still ~$130 so I opted for better performance on the Sony for ~$20 more when I found the
Sangean ATS-909. Confused yet
All of these radios will have FM and AM (MW range like your car radio). Some foreign market radios can have slightly different coverage (like Japan market radios). They are "large" portables to me in that they are not a "walkman" or CD player size, more of a "book" size. For listening performance and features, I find it well worth the slightly increased bulk and weight to get the larger portable radio.
With my radio, I can pick up the BBC and DW (Germany) with its telescoping antenna. I figure that past about 2,000 miles I will need an external antenna. Of course, the signal quality falls with distance and geographic and climatic effects too

. So far, I have found no need or desire to use it for standard AM or FM local broadcasts but, I might do that this evening.
Radio Netherlands was the resource I found to meet my needs best. They reviewed enough radios that I could differeniate things at a common level, as opposed to totally different sources with no common reference point. Also, I found more good information on the Sony 7600G and GR then any other radio or brand. Sangean for some reason doesn't seem to get much user feedback or praise like Grundig (
is it a German vs. Taiwan thing?) but, certainly at the portable radio level, it is very competitive in performance and price. For a >$500 radio, Grundig comes into its own along with several other companies and radios.
So, in the end I would suggest looking closely at the Sangean ATS-909 and Sony 7600GR, with the YB-400 being the Grundig competitor. For a retail storefront purchase, get the Sony 7600GR.
