Nice affiliate link.
I ended up finding a good deal on an older Dell 6500. It was used commercially so pretty much an enterprise unit. It is from 2011 I believe but it has an i7 cpu, 8 gigs of ram upgradeble to 32 gigs, an ssd hard drive and a hybrid ssd drive. The resolution on this thing is very high.
It is a bit heavy and the battery life is maybe 3 hours at most but suits me well. Windows 7..Back lit keyboard.. Every port you can imagine and I can add more drive space if needed.
Got it for well under my budget of $500. Pretty happy with my purchase and I feel a little more secure now knowing I have another back up pc to use when my other units break.. I need to upgrade my main dev pc next. I have not updated it in years. It also has an i7 cpu and it has been over clocked to almost 4g from 2.9 for the last 3 years. It is still as solid as a rock.
Thanks for the recommendations!
