Hey folks, I was away for the Chicago show and refused to use a computer, sorry for dredging this up late. I do think the paragon will heat up faster than the SC, it seems to hold quite a bit more heat.
As far as the small oven, I've done a 12" blade in it, just have to turn it sideways, the SC is fairly wide for being a small oven, so you can fit longer blades at an angle. I don't do too many knives over 10 - 11" anyhow and sending out the occasional large one isn't something I'm averse to. The oven has a lot of limitations, but both the 110V version and the 24" version offer a very good value for a maker on a budget, sure beats a torch and a magnet anyhow.
