I've been looking at small compressors.....Mostly for airing up bicycle tires and blowing sawdust. I don't anticipate using any air tools. I have found some that are oil-lubricated and some that are not. What are the pros and cons of an oil-lubricated system in a small compressor, if any, and does anyone have any recommendations for a specific compressor. I'm not going to be working this unit real hard so I probably don't need a top-of-the-line unit. Thanks.
