I run an equipment rental shop in NY. I know nothing about Xaircraft, I
have a clue about air compressors.
A V-Twin compressor will give good air and good recovery when operated
over a decent sized tank.  Single piston units are S-L-O-W to recover
and typically are kind of buzzy when they are running.
Emglo-Industrial Blue, Rolair, Sullivan are the air compressors of
choice IMHO.  Each of these lines offers an industrial pump, frame,
flywheel, Baldor motors, and good hardware.  Add an oil seperator/filter
and a big H2O trap, maybe two water traps. Buy a BIG tank.  Horizontal
seems to last a bit longer than vertical for reasons I do not know.
When installing,  mount it rigidly with the slightest dip in the
direction of the drain cock. Buy a belt driven, 240 V compressor and
wire it appropriately.  If you have access to 208 three phase you are
better off still. If you must use 120 V single phase, get a 30 amp line
and use the correct gage wiring for your installation. Please note that
a regular household outlet will not supply 30 amps without arcing
problems.  Use an appropriately rated  twist to lock electric connection
and be done w/ it. Put a mesh wire frame over your installation just in
case your high pressure cut off  valve and safety pop off  fail
concurrently.

Sears/Crapsman, Campbell/crumble Hausfield , Dewalt (which is a Black
and Decker painted yellow), and other such are crap.  Note that Rolair
makes a non-commercial, (cheap) line to be sold to the Home Dopo crowd.
Don't buy those.  Emglo was recently bought out by DeWalt.  They are in
the process of separating out the quality to bring it more in line with
the other drek they sell.  Buy an  Emglo-Industrial only if it is BLUE
in color.  You get what you pay for. Buy it once/have it for a lifetime.

Older (20-30 year old) industrial compressors are filthy, oil seeping,
dirt covered behemoths that seem to run forever.  If you find one at a
reasonable price and have the power available to run it, they can be a
bargain at auction/salvage. Old Campbell Housefield's were just about
bullet proof.  Too bad their modern stuff goes Tango-Uniform so quickly.

Hints: bleed the tank daily,  empty the water traps often,  take care of
it and one day it will become a disposal problem for your estate. Stock
a head gasket and a set of reed valves for the compressor head as these
items will eventually need replacing. Having these things ready to go
means you will not  have to pull what's left of your hair out.

If anyone would like help specking out a compressor to be purchased from
your local dealer (not from me), I would be glad to help via E-mail.
