You'll find me on BattleRifles.com in the Carbine and M1A sections... BattleRifles is really pretty much the only other forum I visit on a regular basis, primarily because, well, there is more information on BattleRifles.com if you are a Carbine or M1A junky.
Another good source - though they use 17th century (if that) forum technology - is

Those are some great first stops on your journey...
Next up, I'd recommend spending a little on some research materials, especially if you are going to go USGI and get an 'authentic' carbine.
For the historical aspect, the book "War Baby Comes Home the U.S. Carbine" by L. Ruth is pretty much the bible... here's a copy for $40 - actually a great deal:

For learning about this 3/4 rifle from an operational and maintenance perspective, Duff's "M1 Carbine Owner's Guide" is essential reading... I bought mine from the man himself:

What's neat about the Carbine is that 10 different manufacturers cranked these "Babies" out back in the day, and all the parts are interchangable. I can't vouch for the newer commercial 'knock-offs' in regards to parts compatibility.
Personally, I think USGI is the way to go, not only for reliability and compatibility, but for history and that "Mojo" factor. I like Winchester because of the 'brand' (I live near the Winchester Mystery House) and the fact that they won the original contract.
What the collector is looking for is something 'original', meaning, all original parts with the correct markings... wood stock with the correct markings, etc. There are very few rifles matching this description, as most were rebuilt at one point or another.
The collector pays for this 'all original' status, but it makes not one bit of difference in shootability of the gun. In fact, an all original carbine may become something that you don't WANT to shoot, because it becomes an investment.
That's why I suggest you buy a nice "Mixmaster" USGI carbine... manufacturer doesn't really matter. "Mixmaster" means that it is a collection of parts - the receiver may be one manufacturer, the bolt another, etc.
If you are a brand snob (I'm guilty of this), take your time and search... you may find a Rock-ola or an IBM... Winchesters are fairly common (2nd highest production behind Inland/General Motors), and that's my choice.
I lucked out an inherited a beautiful, all original Winchester carbine (#5670409) for just over $700.... now I'm having another Winchester receiver built up in a restoration so that I have a gun I can really beat on... I feel just a little guilty shooting that Winchester, with its original barrel.
God, I hope I'm not becoming a collector.
Pick up a "Shotgun News" if you can find one where you're at... tons of companies with ammo, parts and other stuff for the carbine. Mags are $10-25 for 15 rounders... Sarco sells a rebuild kit with fresh springs... after 50 years, springs may need to be changed.
Whew. Can you tell I like the little carbine?
