If you have not done so yet, go to the Televue website and read the articles there about eyepiece selection. In particular, the article about eyepiece choices for a small dob (6-10 inch)...not sure if the link will work or not...

The ideas expressed in the article I agree with...
Assuming that you are willing to buy 7 eyepieces at an average cost of AUD$150 per that gives you a budget of AUD$1,050...
This illustrates what I think of as budget eyepiece "creep"...that is, people run out and buy several lower priced "moderately good" eyepieces in a hurry to expand their collection and very quickly spend as much or more than they would have had they chosen fewer high quality ones.
Instead of buying 7 "moderately good" eyepieces for your total budget, I would buy 2-3 high quality ones...these "premium" brands while expensive will last you a lifetime (if cared for) and retain a larger percentage of their resale value should you look to change your scope/set-up or leave the hobby later.
Most of my viewing is done on any given night with just 3-4 eyepeices...a low power, a moderate power and a high power...
3 good eyepieces combined with your barlow effectively give you 6 different magnifications...
As the eyepiece makes up a large percentage of the optical path I'd recommend fewer higher quality eyepeices instead of many "okay" quality...
Make no mistake, if your budget does not allow for the premium end of town, you can still get some very nice moderately priced eyepieces and they will work very well...however, if you are considering spending AUD$150 on 7 different eyepeices, I'd encourage you to re-think your strategy...AUD$1050 will buy you a few premium eyepieces that I think in the longer term may serve you better.
Good Luck!
