Buy a Dob! I had a 130EQ initially because I was impatient! I now have an 8" Newt on a HEQ5 mount, but I will be building a Dob mount soon.
If funds are scarce, then get the 6" - otherwise get the 8". Very good value for money, and still very portable.
If you get the 130EQ and just wish to observe, you will very quickly find that an EQ mount is not nearly as convenient as a Dob mount for setup and use. The EQ mount that comes with the 130EQ is small and light, but not a very stable mount, particulary if you start adding cameras, etc.
Additionally, you will soon want more aperture if you start with an 130EQ.
BUY THE DOB!
Cheers
