well, unless you are planning on installing it somewhere there isn't any 
wind, then guy ropes would definitely be desirable to insure the antenna 
stayed up right for long enough to make your first transmission.
Two sets probably for this guy.  We had a 43 foot vertical bend over in a 
brisk wind last year at the club site.  It only had one set of 3 guy ropes 
on it.  it bent over and touched a 38000 volt power line on the edge of the 
property...let's just say the antenna, matching box at the bottom and the 
radio attached to the antenna were completely destroyed.
Yeah, I know, one should never erect an antenna where it could fall on high 
voltage lines...but we are a ham club after all, we don't pay attention to 
niggling little details like that lol.

Apparently no ground system either but perhaps guy ropes?  I wasn't certain
about that part from their website.  500 dollars not bad for a top loaded
vertical.
