most products when new come with first generation issues, just like tv's xbox ... you get the point. i've learned not to jump on new products the first year they come out, jus wait a little while so all the problems get worked out. i have had many problems with adj products ( i have mentioned them up and down these forums ) and realized that you cannot get the new toys when they first come out. the only thing that i can say that have worked for me fresh out of the box are my htd 4.5 tables and for some reason were discontinued and replaced with BELT DRIVE tables that could never handle the abuse i put my tables through. i cannot believe that gemini has better current tables than adj. just doesnt make sense to me. now i am in the market for a second set of tables and dont have the option of my htd's. nowadays, any table is up to par with techs, exept adj.
sorry to hear about your issues with the radius, but you live and learn.
