mick.. as point for your business perhaps you should concentrate or more 'solid' products.. adapters, wedges, t-mounts, wheel bases etc. things that aren't complex to make but are abit more specialised and aren't mass produced.. Wheeled bases would probably be your best bet for a new product as it is something that almost all astronomers could use, so you've have access to a large market providng you could cater for different types of scopes/mounts. It may also be worth down the track looking a truss dobs and parts, as they are large and bulky and a pain for shipping.. so there would be a local advantage, but a smaller market there.
