I've used a lot of print/cut combinations the CJV is as good as it gets in my opinion. Don't expect perfection from any of them, but it rarely does a cut that you'll have to reprint. Reading your original post, loading will be critical if you are cutting something that long. If you get it loaded correctly it should cut ok.
Speed/Quality, really hard to say since that is sort of subjective. To be honest the HP latex machines are hard to beat quality wise for the price, but the CJV does a good job also. My friend mainly prints on 16 pass, but most people from what I've read print on 8. Your best bet would be to watch one print at a show and judge for yourself on speed/quality.
