Dave,
From my perspective, if it was that simple, there would already be a cheaper version available on the market. But I may be wrong.
This sounds like a great business oppotunity for somebody, because there would be a profit margin of at least $1000 a unit and regular cruisers would line up to buy them. Sales of more than 100 units a year seems pretty reasonable. I look forward to reading the measured results from the first successful version that costs 1/5 of the current retail price.
Fair winds,
Eric
