Router or Biscut Jointer
Glad to see a thread on this subject! I've been thinking of getting a laminate trimmer for this sole purpose. Harbor Freight (cough, cough) sells 'em for 25 bucks! Sure, they're nothing fancy, but how fancy do ya have to be to spin a cutter bit? A 5/32nd " router bit with three bearings for 0, 10 & 20 sized biscuts is less than $50.
Who needs a 100 to $200 machine to do the work of a light, tiny, single-hand controlled tool? After some initial practice, the reaction of the tool when the cutter hits the wood will be easily overcome and mastered by lovers of the trade.
