Well, I guess we are all different, so kind of hard to say wich you "Should" do....But, for me, I have enjoyed building my own.
I started w/ a very simple set-up w/ carpet & aluminum L brackets for the riffles... I used it once or twice & decided I had to go back to the drawing board. (had no idea how much angle, water speed, how far to classify, etc...would it even work ?) Looking back now, that has been half of the fun.
I found post's on this site about the fluid bed gold trap's and was hooked. I found a metal co. close to me on the internet, was in Hayward, Ca. Spent $20-30 on a bunch of aluminum & aluminum scraps. Tools were a pair of tin snip's, pop rivet gun, corless drill, and some hammers & Files & clamps....
Get "almost" as much fun showing that thing off as I do the gold I've found. (And it works So much better !) After the holidays I am going to make a "prospector" size that can run a lil more material....
