I run the ws6store catch can that Adam linked plus a LS6 valley cover/pcv. Thats the best quality vs price can Ive found, and the size is reasonable for mounting. I have very little oil caught in the can with that setup, maybe an ounce every 3-4 months, and my intake comes off pretty regularly so I know the ports are clean
The sight tube on the side is nice, but the low cost ebay can I tried was a POS. fittings leaked, threads were galled from cheap chinese metal, and the filter media packed in the outlet disintegrated into the can and blocked the drain.
Go with the ws6store catch can and get a 1/4" NPT ball valve to hose barb to replace the bottom drain. Add a ft of hose to the drain barb, and you're good to go.
