I think Frank's pricing was based on a complete unit, not the kit version. In any event, I agree with WEEZ, most build kits to save money and personal fulfilment. Even if one doesn't have a working Dyna ST-70 to transform, with transformer bundle from Triode Electronics for $269, new chassis from $99, and if one springs for Frank's full kit at $449 as opposed to just the board and plans for $149, the total cost would be around $817. Less if they chose board and plans. Consider a few miscellaneous parts and the whole thing can be build for under $900, less than half of a complete unit from AVA. So for Frank to "pull the trigger" as he states, I would imagine that there would have to be a greater demand for factory built units. Given the type of folks we are, maybe there are more of us who would rather build than buy the complete unit. I don't know if Frank can get the kit version down in price close to $900- $1000. So you can't blame Frank for not moving forward without sufficient demand for the complete unit.
I would contend though, that Frank may be more successful at getting the current installed base of Super 70 units upgraded to Ultra 70 status, as well as getting original ST-70's upgraded to Ultra units. To that end, making the chassis available as a retrofit for those who currently have Ultra 70's in less than beautiful chassis would also nudge those who are on the fence in considering upgrading stock or Super 70 units to Ultra 70's. Even if the new chassis was 3 times the price of the current offerings at $300, I think he would get a lot of Ultra 70 customers ordering the new chassis. I'd go for two of them. This of course does not help the music lover who can't/won't pickup a soldering iron. So, as I said, one would need to know what the true demand is for the product and in what version, kit or complete unit.
