A-MAZE-N Stainless Steel Black/Silver Tube Smoker https://www.amazon.com/dp/B0765C4LML/ref=cm_sw_r_apan_glt_i_Z8CNR8JWSQGH4K5ZJTN7

This is similar to what I use. Mine usually runs for a couple hours between pellet refills, might be the 8" version. Works great for cold smoking. Regular smoking is done via conventional means (lump and wood chunks).
