Speaking of buttons and the Ascension, there's an outfit called MAI, out of San Jose I think, but this fellow Hong has a very nice replacement button for the soft touch OEM. $75 bucks a pop, but if you saw the quality of this button and how much it looks like the original equipment, you'd be pleasantly surprised. It's completely mechanical similar to an older Adams, but a superior design in materials.
I don't believe he has the early US soft ouch P.I. lamps though. Anyway...just I'd pass that along.
