If you have a spare corney - this might work for you:
Total cost: ~$30 (cheaper if you already have parts)
Take a small bucket ($6), one 90 degree threaded pvc piece ($~4), buy a plastic bottle blaster ($15) and a liquid pin-lock ($6), one piece of high temp tubing and connect it all up.
I just get hot water from upstairs in the keg, pressurize it to ~55 psi and plug it in - works like a charm - just be careful when you plug it in
I soak my bottles overnight in PBW and have a vinarator on my bottle tree.
One-stop - no sink required - bottle washer.
All inspired by the ladies and gents here at HBT - thank you all.
