This will get you into photography at some stage as well.
I started out with buying a Meade PST 125 PE, Meades version or similar to what you posted above. Cost me an arm and a leg i think it was about 2.5k and it was a piece of crap. These celestron and meade SCT's or Maks have great optices but the mounts are really crap.
I've had an HEQPRO5 and it's a great little starter. Not the most accurate and the learning curve will be more, a good deal more but you wont out grow it anywhere near as quickly as you will the 6SC.
