This is going to sound like spam - I already know it - but I don't work for them. I've been trying to find an original PDI-03 for a couple years but couldn't. Too hard to come across and WAY too expensive. I placed bids on a couple but my maximum was outbid quickly. Palmer is just now starting to roll out a rereleased 03 speaker simulator with all of the original specs, down to the knobs and switches, which took them quite a while to track down. I've heard what they went through to ensure that this rerelease is exactly like the originals and I'm comfortable that they'll sound and function identically. Mine arrived a few days ago and it's wonderful. I may still record with a cab from time to time, but not often. Doesn't seem necessary at the moment. FWIW, these can accept 100 watts at 8 ohms and have a few tone shaping options to simulate different types of cabs. For the most part, I've been using the Flat settings.
