Just because I like playing devil's advocate; you have to admit there are other issues not including the extra $500 in price. I could be wrong, but when I worked in hardware, the stand-up oiled 2-stage compressors had to be hardwired, which is fine so long as you have a spare 220 volt circuit and either be confident in your home electrical skills or have a good buddy that is an electrician.
The footprint of the stand-up units is actually smaller than the horizontal roll-around type, but it is a lot taller, and you can't just roll it under a workbench or back into the patio (if you don't have a garage) when you're done using it. Some people just don't have that kind of space or even have a garage. And the last issue (mind you, it's been years since I've been in hardware and things might be different now), but there were issues with laying the upright models down even for shipping. So you couldn't just strap the thing on to your roof rack. Extensive lashing had to be done to stand it up in the back of a pick-up whenever we sold one. So, figure you've got an extra $500-$600 and possibly money for delivery, money to pay an electrician to atleast wire it, if not install a 220 volt outlet nearby where it needs to sit almost indefinately. -Terry Yahoo! - Official partner of 2002 FIFA World Cup http://fifaworldcup.yahoo.com /// [EMAIL PROTECTED] mailing list /// Send admin requests to [EMAIL PROTECTED] /// or try http://www.team.net/cgi-bin/majorcool /// Archives at http://www.team.net/archive /// Send list postings to [EMAIL PROTECTED] /// Edit your replies!
