I started with a homemade wood sluice with drop riffles but I noticed it started to warp quickly. I must of not sealed it well enough. I then purchased a Keene A52 because I like the idea of being able to add things and turn it into either a highbanker, recirc or power dredge. I built a snap on classifier that covers the first third or so of the sluice and added additional v matting at the start. I've probably doubled the amount of material I can run by not classifying and ditching buckets for a barrel sled. The Keene is a heavy sluice so if your packing things a far distance it sucks for that. I've heard good things about Le Trap and Angus sluices, light weight plastic good for packing in distances. The bazooka comes to mind also, constantly hearing praises about it. One con I see with the bazooka is that there is no way to see if your in the gold without a cleanout. Other sluices with v matting it's right there to see. Really a quiver of sluices is ideal, a good addiction doesn't allow you just one!
