I've got a 15" mid-2010 Macbook Pro for sale. 2.66GHz i7, 8GB RAM (my upgrade), 512GB Crucial M4 SSD (my upgrade), DVD writer superdrive, and what was at the time the high-res screen option (matte 1680x1050) with the discrete Nvidia graphics with autoswitching. UK keyboard layout but I bought a NZ plug for the power supply when I moved back here. The logic board was replaced free by Apple last year as it was subject to the Nvidia failure. The replacement board has run without problems since then.
At the moment I've got the Yosemite public beta running but will happily put a fresh Mavericks install on. I've been using the Trim Enabler app to keep trim support enabled on the SSD almost since the beginning.
There are a couple of known issues with it. The first is that about three years ago I managed to slightly deform the aluminium body above the ethernet port. I have never had any problems with the ethernet port though, and as far as I can tell it's in perfect working order, just a visible flaw (see the attached pic).
More annoying, and my main reason for biting the bullet and buying a replacement is that the two USB ports and the mini DisplayPort connector don't stay connected reliably. E.g. I almost always use an external screen in addition to the builtin one, and when I plug in the adapter the screen might or might not be recognised, and the tiniest of movements could cause the screen to disconnect. The same is true with the USB ports - thumb drives easily disconnect from almost unnoticeable movements such as vibration on the desk from typing. I've had an Apple service provider look at it and they reckon the whole logic board needs replacing *if* I want to correct the issue.
Anyhoo, given that it's still a pretty decent laptop I figured I'd see if anyone here would be interested - obviously only if you don't rely on USB ports or external screens.
