I would rather stay in the 1K range and I have heard the "stay with the local" more times than you can imagine.
Hrrrrmmm... I bet I've got 20ish Dseries Dells in service for my friends and family and my old job. The only one I dont' like that much is the D820 but it's been fairly reliable (esp. compared to Caleb's).
At my current job, we standardize on the Dell D4xx series. They are SUPER portable, but not much of a desktop replacement like the 6xx series are. I'd estimate we have at least 4000-5000 in service around the world and the only real issues we have with those are hard drives that start running RE A L L Y slow.
Personally, I'd rather not deal with a "custom" built machine (I can "custom" build my Dells to my specs) with the various hardware flavors out there. For the few times I've had to ask for service on the Dell D6xx series, I'm quite happy with them and will continue to recommend them until they totally suck. They identify a problem over the phone, send me the replacement parts EXTREMELY fast (sometimes within 18 hours) and I replace the part and send the broken one back.
I've bought the refurbs (they ship faster than a custom machine that could take a few weeks to get to you) that were spec'd how I'd buy a machine and have only had an issue with one machine out of about 20 (which happens to be my wife's
). I'd look at the Dell Outlet refurbs again. Sometimes there are some SCREAMING deals in there.
Oh, and I've tried to convert to the iReligion. It's fine and the hardware is SUPER nice, but it comes at a premium price and has a bit of a learning curve.
