We have always let our customers speak about their own experience with us and our products. A happy customer might tell a friend or two. An unhappy one will tell the world.
We build controllers for people that don't want to build their own. We have been building controllers for a decade, and we are always improving them.
We take care of everything we build as long as you own it. If you have a nine year old controller and have a problem, all you have to do is send it to me. We'll repair it and send it right back.
We have always favored analog power control for the kettle vs manual control mode on a PID using up/down arrows. All of our controllers feature this, and there was a time (until around 5 years ago) when we built our own power control module with discrete components (TRIAC based with a DIAC trigger for symmetrical firing). We did use a short run of 10 gauge speaker wire during part of this period because it was much easier to solder to the board. These days we use a 40A SSVR for the 240V controllers, and a 25A SSVR for the 120V controllers.
Some of our controllers also have mechanical relays (we have not glued them in for several years). In some models these relays are used to switch the other hot leg off when the heat is switched off to ensure that the receptacle is completely de-energized when the heat switch is off. Some controllers out there only switch one of the hot legs. The EBC III-D uses a 30A double-pole relay to switch the HLT heat on/off, and a 25A relay for the Pump1 output in case you want to plug a 120V RIMS heating element in instead. Mechanical relays are used where switching is infrequent, and normally last for many years. If one fails we replace it.
The cost of the components for any of our controllers vs the retail price of the finished unit is in line with typical retail store pricing, and we still have to put them together. You can save money if you want to build it yourself, and your time is free. You may just enjoy designing/building it.
There are now many choices available for those who would rather not build their own controller. We know a lot of the guys putting these together, and we all have our own approach. You should take a look at all of them and decide what fits you best.
