Micko, try comparing the 19mm Pan with the 20mm SV if you get the chance.
OTOH, there is the Stratus and Hyperion EPs that can be had for under $AU200. Stratus work very well in my f6 and reported to work well in faster scopes too. The 60 degree Pentax XFs should also work well at not much over the $AU200. (but only come in 12mm & 8.5mm. I'd really like to try one of these!)
