Where to find paradigm x-30 cheap (1 Viewer)

[Greg P]

I am finally getting a x-over for my SVS and I think the x-30 is one of the only options for my budget. I found it for $120 used on audiogon but only want to spend $60 $90 at most. There is an auction on ebay for an x-20 which I think might work. Does anybody have any other ideas.
Thanks
