I have a 36" Northern/Harbor Freight quality cabinet. If it's just for occasional hobby use, it is OK. I WISH I had a 48". If he upgrades anything, get a bigger size.
I've looked at those Scat cabinets a dozen times, but can't pull the trigger. Too many car parts to buy...
I have a 5 gallon shop vac for dust removal with HEPA filter bags to contain it. Nothing fancy, but it has hundreds of hours on it.
I buy glass and sand at Northern Tool. Harbor Freight sells media and also Tractor Supply. I have all of them nearby.
