Where to buy the T530 w/quad core?

[Arf the Lab]

Hello, all.

My current office computer is a T500, I'd like to replace it with a T530. I want one of the models sporting a quad core processor (i7-3630QM, i7-3720QM or i7-3820QM), but I can't find either of them for sale anywhere online, new or used. Tried Lenovo's website, eBay, Amazon, web searches, etc., but seems only the dual core models are available.

If someone could recommend a trusted source to buy this machine with one of the quad core processors, I'd appreciate it.
Otherwise, if there is a comparable (or superior) model available, that can handle at least 16GB of RAM, I'd like to know about it.
Once I get a newer machine I can relegate my T500 to that of a travel laptop, replacing the well-worn T40 that's been accompanying me for so many years.

Thanks in advance.

Why not get a dual core and upgrade it yourself to quad core?

I realize this doesn't help find the computer you are looking for, but there was also an i7-3840qm available.

W520s and W530s came with quad-cores, perhaps that's what you're looking for.

I wanted the T530 but ended up buying the W520 w/the i7-2920XM processor anyway. I think it'll suit my needs well enough.
