I've seen a few DIY models like the one shown. Evidently they work fine? I started pricing parts on one and the motors alone were 80.00 so I was figuring I'd be in it almost 175.00 by the time done as I've seen the $100 price a few times for DIY but just did a preliminary look at that? Evidently I'm looking at the wrong parts. I may have to take a second view. Cannot seem to part with 275.00 for the Annealeez.
