I bought one a couple of years ago and used it while in Colombia with my
Arrow, FT-817, and FT-857.  It worked well for my FO-29 contacts.

Do heed the warning about transmit protection, in swapping radios/coax I
forgot to switch the preamp and the 857 at 10W blew the preamp,
fortunately it was at the end of the trip!

My thoughts, if you're going to use something with an Arrow in an easy
setup where you don't have remote/automatic switching and you're
possibly portable and such, it seems like a good place to start because
if you do mess up it's less of a loss dollar-wise.  Just be sure to be
sure before you transmit.  If/when you set up something more permanent,
as you said there are much better but more expensive options.
