Car Stereos: Radio substitution question..., gm radios, buick lesabre

Question
Scott,
I've got a 2001 Buick LeSabre, with a factory AM/FM CD/Cassette radio.  The radio is no good, and I want to replace it with the same OEM model.  I've found a website where I can buy a refurbished one, and I know that this model radio has a "theftlock" feature...and I'll have to take it to a Buick dealership and have it reprogrammed (or reset, whatever you call it) so it will work with my car.
But also on the same website, they have some radios advertised as:
"AM/FM/CASS/CD: FOR A 2000-2004 BUICK LESABRE WITH BARB ANTENNA. DOCK AND LOCK RADIO. NEW STYLE"
And it looks like this radio...though it doesn't look exactly like the factory one I have now...would fit.  (My current radio does have the white "dock and lock" connections.)  And this radio is advertised as "plug and play", and not needing to have the code programmed...because they are currently unlocked, and will learn the vehicle VIN when they are plugged in and will then only work in that vehicle.  And that would save me both the trouble and the expense of taking an OEM radio to the dealership to have re-coded.  (The website is:
http://oem-auto-accessory.com in case you want to review it...the radio I'm looking at is listed under the "Factory GM Radios" submenu.)
Without being able to guarantee it, of course...does this radio look like it would fit my car?
Any advice/suggestions you could offer is greatly appreciated.

Answer
Yes, it looks like it would fit your car, and the website says they will cross-check your car and send you the proper radio that will work for your car.  It looks like a pretty good deal.  If the radio does not work or does not code itself to your car, they will return it no questions.  Hope this helps, Scott
