[TenTec] Jupiter or Omni

[Able2fly at aol.com]

All,
 
I need help in making the proper decision. I''m just a 90% CW, casual  
contester, occasional DXer, barefoot/dipole kinda guy. I like doing QSK at  maybe 40 
wpm max. Most important, I like to work QRP and pull the weak ones out  of 
the noise.  Never owned a Ten Tec. I want to try one.
 
Do I want to start with a Jupiter or Omni?
If Omni, Which model? And why?
 
Advice will be appreciated. 
 
73,
Bill
