I would advise against a 2010 as they won't be able to take advantage of the full speed of modern SSDs due to their lack of SATA 6 Gbps.
Although that's true, my 2010 MB Pro 15 inch with 240 GB SSD and 8 GB RAM, flies like a fighter jet. I'm not sure what the speed difference is between SATA 2 and SATA 3, and I really don't care. All I know is that my Macbook boots up almost instantly, and loads just about everything I throw at it (Photoshop, Office, etc.), in mere seconds.
I went up to the Apple store the other day to look at the new MacBooks and wasn't real impressed with their speed. Sure, they're faster, but it's like milliseconds over mine. I'm mean, seriously, I could take my Macbook up to the Apple store, put in on display as a sales demo, and other than the screen being a non-retina screen, no one would be the wiser.
So, my advice is to not be afraid of a 2010 Macbook Pro. Get it, load it up with RAM and an SSD and you'll be just fine. And you'll have a little money left over in your pocket to take your girl out to dinner.
