I purchased one off of Amazon, It was about $12. the Fantastic that I am using was a used model cut out of an RV. it appears that the bearing is going out so it is making some whining noises and clunks at lower speeds. I am hesitant to recommend this particular PWM right now because I read that some will cause the Fantastic to whine. the PWM frequency is too low for that motor so you end up hearing that in the form of a whine. I have a second doner Fantastic in the garage that I just tested as is. no whine and no clunck. I will be swapping out to motor assemblies to try to eliminate that whine. I will update as soon as I find out.

This particular controller used to be a "color" on amazon with about 12 different PWMs all "colors" of a single item. as a result, the reviews were all jumbled together. the price range was about $8 to $20 depending on the amperage, form (some had pots directly attached to the board while some had a 6 inch wire to the digipot like this one) along with lights and switches being attached. on the reviews then some of these PWMs did NOT work well with fantastics. at $12 I thought it would be worth the risk to see if this one is. NOW amazon has them all as seprate items. the few reviews for this particular board look good, but no confirmed fantastic conversions yet.
I will update this once I do the motor swap and will also post a review to amazon.
also, I can vouch for this particular board being able to (barley) fit into the fantastic shroud. but there are several options in this price range. I ended up going for this one because it had both a forward-off-reverse rocker and an infinite adjustable pot all with 6 icnh wires to provide the greatest mounting opportunity. (board in one spot with controls mounted a few inches away)
I'll also add these few threads as a separate thread. and I will take some photos of the board in the shroud if I need to take it apart again.
