need a good 8 inch sub.. suggestions?

Sorry man,, I forgot that I also have an HX2 avail. although the price is a little higher.  I am stocking up for a used venue here in town. 

I didn't think about this one until later, also meets your specs, Image Dynamics ID8 V.3. They haven't updated the ID page to include the V.3 yet, but you can find the specs link on the tech page.

Ok guys.. I think I've decided on the JL Audio 8W3v2, they almost reflect my needs perfectly..

I just won that amplifier tonite, ill bridge two outputs for the 8" sub.. and it should work nicely with the 8W3v2.. anyone know where I can get one of these subs cheap?

The only internet shop I found was:

I haven't ordered from thembut someone else may know how they are.

Since you are an EBayer, you've probably found these already:

Since the 8 is not one of the more popular sizes you'll probaby not find alot floating around for sale.
