I suggest looking at the Auber site and noting PID controllers vs PID kits. Look at the supplies and see what you want and then see how much you can save on Ebay. The Auber RTD sensor is probably the best for Gaggia, fits the brew stat port.
Do you want a box to house the PID?
I helped a fellow in Canada and he ended up with Auber equipment, not kit, and then bought wiring and connectors from Ebay.
Before you buy a PID, make sure that there are good instructions. I have not been able to help much with Sestos PIDs. Not all PIDs use P, I, and D to mean exactly the same, difficult with some Chinese clones. I have not look specifically at the one you mentioned. Here are generic PID instructions, almost identical to Auber, but not exact for Sestos.
Do you have easy access to electronics, wires, spade connectors, and perhaps power supplies such as cell phone chargers?
You can find a lot of info on the PID thread below. If you are good at understanding the electronics, I recommend a PID with PID algorithms and 2 alarm functions. The thread has about 15 pages of how to use a PID alarm to stop intrashot drop, and how to use a PID alarm for steam. Pages 16 - 30 are a fairly complete install on Gaggia. If none of that seems fun, consider a kit.
Wire from a used computer power cable, crimping connectors from Home Depot. Works perfectly. The PID I got has SSR output and two alarm functions, and it's easy to setup. But I decided to leave the steam temperature on the original thermostat.
The only "more difficult" part of all this is to find a suitable small case that is aesthetically pleasing.

If you read the PID thread above you will see that with a 1/16 DIN PID with 2 alarm functions you can have brew temperature, add heat with brew for stable intrashot or controlled temperature drop, and steam control. The first half of the thread explains all of that in comparison to steam switch surfing so that you can understand it. The second half of the thread will tell you supplies needed and describe what you need to put together. Brianl asked a lot of good questions that clarify most of the install. If you want to proceed you will need to gather supplies. I like the Auber supplies mentioned in the thread.
I believe this is an inexpensive project box for the squarish 1/16 DIN PID, Model: 270-1803
