Hi there Matt, welcome to the forums!
I'm guessing you did mean to say the DJM350 rather than CDJ350 in your post. I think you'll find the quality of the DJM350 quite impressive, even in comparison to the top of the line DJM mixers out there.
I like to bring my 350 to some of my more mobile gigs as its a snappy little unit to pack in and stands up to a bashing. Going for a second hand DJM, by comparison, you don't know what issues it may have or what damage the user inflicted on it.
Quite honestly, I would think you'd like the unit and it would fit your needs. I would, however, encourage you to go test it out at a local store etc if the opportunity arises before you purchase.
