Suspension Forks for under $500AUD

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

Pretty soon I reckon my Judy TT's could use replacing.
What suspension for aroound (or less than) $500 AUD are good value for money with reasonable performance?
I'm on a 2001 Specialized Hardrock Comp.

I was looking at the likes of :
Rock Shox Tora
Rock Shox J4
Rock Shox SL
Rock Shox Pilot SL or XC

Manitou Black Elite
Manitou Splice Super

so would you recommend any of the above or have other suggestions? And Why??

(yet to convince my Husband though! - may have to give my share of the alcohol budget to save for them, but since I don't drink that much it would take years!!)

Thanks for your imput in advance...
