Hi there,
have a look at the ad Sylvain has put up for the TMB type II Planetary 6mm & 9mm eyepieces. I have the 6mm, and all I can say is WOW! Now I'm getting the 9mm too, and for $49, they are a steal!

You won't find better high power EPs for this price anywhere!
The 6mm will leave a barlowed image with your 12.5mm for dead.
Hmm, just looked at your avatar, looks like you could be a little bit further out than a couple of hours drive from my place,

.
If you're in Sydney, you'd be most welcome to try out my TMB 6mm first. They really are so good.
