I built my own extension, but I have seen them on eBay.
I did my leaf springs and drive shafts in there- do one end, turn around to do the other.
Plus I built a base that made it taller, with wheels. I don't want to work TOO hard, this is supposed to be a hobby.
And I did make the cylconic dust collector, from a Chinese blower, $15 at the swap meet.
In use, the DC has enough volume from it's 1/2 hp motor that I leave the trap door open at the bottom of the hopper. Keep a plastic pail under it. The good sand drains out, the dust gets sucked up. Then I pour that sand into a $69 Harbor Freight pressure pot. It works about 10x faster than the suction feed that comes with the cabinet.
I use a 4hp and a 3 hp compressors, hooked in parallel. Then regulate to 45 psi. And use the REAL pink alumina nozzles.
The link also has pics of using a tent around the frame, axles, etc. I hook up the DC, add a 2' piece of pipe to the sand blaster, and insert that lance through an un-zipped seam of the tent. There is no real pressure to push the sand out the visqueen, the DC takes care of it. Then, move the tent, screen the sand while shoveling into a trash barrel, and re-use- 2 or three times.
YMMV, mine sure does!
