I'm considering the Nova monochrome...'
Is this system as easy and hassle free as it looks?
Messy?
Should I buy extra clips? (Largest I do is 11x14 b&w fiber prints).
+ 1 for the Nova units. But unless your darkroom is a steady 20C / 68F all the time you want to print, I would look at spending a little more on a unit with thermostats built in. I've used my 12 x 16 for years now and the temperature control really comes in useful in the darker, colder months, as my darkroom is unheated in an outbuilding at the end of the garden.
Easy and hassle free? = Just about. I can't think of any problems when compared to trays. I, like others could list a lot of positives for getting one though, but for me especially is the 'just turn on, warm up and work' ability of it. And chemicals can last for months rather than 2 days most compared to trays. But for me it is the ability to leave it set up and then able to do 10 minutes to 10 hours work with it, as and when once the chemicals are the right temperature.
As for extra clips, well some will say you only need one or two, as all that needs to be done is to dunk wash and then shake them dry, which is probably okay if you've got water plumbed in as well. Well, I haven't, so I have bought a few more clips secondhand off of ebay over the years, which in turn enables me to spend a while in the darkroom before retreating to the house sporadically.
But all in all, a great idea and product although a bit expensive purchase, but well worth it in the end.
