Can't go wrong with Seal, they are the best. We have one and love it. An Upgrade from our 44" Ultra which was a POS compared to the Base.
Only real decision was between the Base and the Pro. But we couldn't warrant the extra cost, since we only do cold lams. Pro has a bigger roller and a swing arm. If you have an extra 4-5k burning a hole in your pocket go Pro, if not you'll be happy with the base.
Ohh we got the heat assist option as well. Helps on a few jobs.
