Either the 625-2 or the 625-3 are excellent versions in 3, 4, or 5 inch barrels. My personal favorite is the 625-2 in 3 inch barrel. These are still pretty easy to find in excellent condition and you will not pay much more than you pay for a dash 8, which I consider to be inferior in many respects.
So if you want the best 625 out there, take the time to find a quality dash 2, 3, or even 4.
But if you, like so many people, just have to have something new, then go for the 625-8.
Comes down to what you want to do with it. I went with the -2 because I could score higher with it in Bullseye. I don't shoot BE anymore so I'm happier with the JM Special. My BE guns were strictly utilitarian (except for my custom 38). Like a Ginsu steak knife, they got the job done very well but were not something I was emotionally attached to. The revolvers I have now are different.

Thanks. I actually ended up finding someone on this site that was looking to trim down his collection and was selling his 625-2 3", so I just bought that from him. The price was fair and I'd rather help out someone from the forum over some random pawn shop on gun broker.
For those familiar, I didn't even know they made a 3" 625-2. I thought the 3" and 4" models weren't available until 625-3. Did they make some while in the transition phase and still printed 625-2 on them or something?
