I'm interested in buying one of these but have a few questions:

1) Does anyone besides Nova make them?

2) Is there any good way to keep the chemistry below ambient air
temperature?  A few models have heaters, but keeping things cool seems
to be more difficult.

3) Is an 8x10 unit suitable for doing 8x10 prints or is it
advantageous to go up a size, a la regular trays?

4) Are the fiber-compatible models really worth it?

Sorry don't know, however people do try homemade...

Pouring iced water into the cavity might do it?

No advantage to going up a size with Novas IMO because there is some
allowence built in for agitation and also minimises chem usage.

Sorry don't know--other than have used mine (regular models) for fibre
only and the clip seems fine having dropped only a couple of prints
because of tearing/slippage...

Jobo used to make one, the Jobo Prima. Production was stopped due to
problems with Nova - or their combined US-efforts.

Sometimes they surface at Ebay at loooow prices. Mine cost me 15EUR
incl. postage...

A cold water bath?

No, it´s ok.

I don´t know. My Jobo works with FB - the paper holder is different
than the Nova, not a clip clamped on top but a long stick. You pin the
paper on the bottom, the paper is supported by the stick.

 Evaporative cooling won't be of much help with a slot processor.
I've a new furnace and central air-conditioning in mind before
summer, but that is a whole house priority.                   Dan
