I am thinking of buying a new Pioneer DVD player and want to get it from Techtronics as: a. They are the cheapest (from what I can see) b. Their mod doesn't require soldering, as it plugs in the little slot in the side. This means that it could remove it if I ever need and it won't invalidate the warantee. How are Techtronics? How are their mods? They claim to be the most experienced in this area? Has anyone had any problems?
