Hi Stu,
I use a Hyperion Click Zoom 8-24mm ep. The Hyperion stuff is excellent quality and the benefits of a zoom of this quality are significant. When I bought this, they were about $350 here and only $220 (posted) from the US - so I bought from the US. The exchange rate is better now so it may be as cheap here.
The ep is also parfocal - meaning you don't have to re-focus every time you switch magnifications.
Other than that, the Televue plossls are great value at around $150 each. Of course, if you can afford the top end TV stuff, that would be a terrific addition to any collection, but they can cost as much as some peoples' scopes
