dvr or multiplexer

[larr3y]

any good multiplexers out there to use for preview monitors

needs to be 9ch

found this seems expensive considering there is no recorder

should i just get a dvr or actually buy three 3 way marshall monitors and forget this whole crazy idea about dvr s and multiplexers

any ideas

thanks larr3y
