I have a Seal 150 as well. You're going to love having a dry mount press! IMHO, nothing looks better than a dry mounted fiber print. FWIW, I've found that Seal MT5 tissue is far and away the best. I've tried cheaper off-brand tissue and it was a disaster.

My press' thermostat must be off, but I've found that a meat thermometer works just fine for setting the temp.
