Ebay is $199 from the same seller I got my XTR2500.1Dz from (Paid $360 shipped), but you can also get it for $195 shipped (205 - 5% discount code) from Online Car Stereo which is where I bought the 1000.1D I had. OCS is also an Authorized Orion Retailer.
Only reason I didn't mention the PPI is I saw Soundstream killed off it's version of that amp (TN1200.1D), along with Polk and I'm not sure if Precision Power's version is next or not. NVX I think will be the final hold out as their entire line is made off that series off amps.
