know nothing about Legacy. but...
just started working with another shop that usues a Laguna.
His machine is built like a tank. Integrated vacuum table. power, oh my god, power to spare. now his machine cost 4x mine so...
I will say however that I regularly do file conversions for him. Help him work through tortuous settings modifications in order to do weird stuff, etc.. We work primarily with artists and designers so we do a lot of odd one-off strange projects.
Without a doubt my shopbot software/machine integration and ease of use makes these strange projects much easier. And the support from the company and this forum simply rock. Especialy when I am trying to do something that the machine wasn't expressly designed for. The DIY ethos and ingenuity of this company/community is amazing.
When we need to power through 1240 brackets in 5/4 stock, his Laguna is the clear winner. (caveat: see price point above)
So as always, decide what you want to be doing and buy the best tool for the job.
Do not follow where the path may lead. Go instead where there is no path and leave a trail.
