Re: What do you guys think about this compressor

After hearing from you guys and researching online this is what I've learned about "What to look for in a compressor":
The following is for 5HP 2 Stage 230V single phase with 80 gallon tanks
Pump RPM - Less expensive units (under $1500) usually have small cylinders so they have to run at higher RPM's to produce the same CFM output as larger cylinder low RPM Pumps. The higher RPM means noisier, and they wear out fast. Most units I've found in the under $1500 range are the small pump, high RPM version. The point - Look at the RPM, LOW RPM and High CFM is good. Also make sure rebuild kits are available for the pump.
CFM for compressors, as mentioned above, are generally going to be in the 17 to 19 CFM at 90 PSI range for the low rpm larger pump style compressors ($2000 range). Units in the 13 to 15 CFM range usually have high rmp pumps but are lower cost units ($1000 range).
Lubrication - Two types on units above: splash oiled and pressure oiled. Pressure oiled is better but is also usually about a $500 increase and generally found on units that are in the $3000 plus price range. Plan on splash oiled.
Starters - Two types on units above: Magnetic and flip type switch. Magnetic is better but also about a $250 increase. Some brands offer the magnetic starter as an option. Most if not all units in the $1000 range are not going to have a magnetic starter.
Some name brands I've found that appear to make good units worth looking at in the $1500 to $2500 range:
Eaton (Polar Air)
Quincy
Saylor-Beal
Champion
Kellog-American
Ingersol Rand
Box Store Brands that offer low cost units that will get the job done for the backyard hobbyist and seam like a good value for what the are:
Husky (Home Depot)
Northern Tool
