You can special order the pressure lube models through NT... Fortunately for me there are actually a few different authorized Quincy dealers in town, but prices are pretty much fixed for new models. Sometimes you can talk them into a few bells & whistles for freebies, but that's about it.
The pressure lube models do have a longer warranty...
In all honestly, for the duty cycle that *most* people use a compressor... I don't think there is really any difference in splash vs pressure. If you are getting into the serious industrial setting where it will be running a lot higher duty cycle, then yeah a pressure lube with the spin-on filter would be the way to go to ensure longevity. However you still will have to perform regular maintenance and clean the valves now and then... sooo....
But anyhow, I would rather spend a little extra for a QUALITY compressor and also one that is made in the USA. Not necessarily a Quincy, I really like the Saylor Beall, Kellogg American, Garden Denver, and Champion compressors too. When shops depend on air to run their business, downtime because you have to rebuild a cheap chinese pump will probably cost you more in downtime than if you just bought the better compressor in the first place.
The new IR pumps everyone says is garbage. They source parts from all over and the quality has really gone down hill for their models that you find at like Lowes and NT. Older models seem to be much more reliable though.
