Have seen that 'Dual-saw' advertised on TV. Lots of questions! Any good? Specialised uses? Under powered? May be worm drive? Seems expensive, for what it is, (around $180) as advertised on TV? Main advantage might be the lack of 'kick back' in certain cutting situations? Other?
Also: BTW what about that 'undercutting' reciprocating gadget; enables one to cut close to floor or to cut apertures into, say a wall, etc. Looks like be OK if one was doing flooring? But how robust?
Comments on either/both welcomed. TIA terry
