This post echo's an earlier question I asked but now the need to obtain an answer is much mor pressing. How does a Phase 100 compare to the phase 90? That's it! It's just that I have less than 20 hours left if I want to buy one. It's a vintage model (old "phase 100" script, joined up writing style). Any idea what these models are like? Should I avoid it like the plague if I can't try before buying? Thanks in advance for the responses!
