You are certainly more at risk draining your filter with a sunsun and starting your house on fire with a Odyssey (sp?). I'm sure you have been around the hobby longer then your join date would suggest but I have been on this forum for some time and have seen my fair share of catastrophes with less than quality equipment.
See I have not seen that so until I do I guess I will be a risk taker. The old Odyssea lights I have heard of having problems but have you heard of any issues with the newer ones? Also I have never heard of anyone have there filter drain with a Sunsun (or any other filter for that matter) if you have I would love to see the thread to see what to avoid. Regardless no one is going to talk you out of your high priced fancy equipment and no one is going to talk me out of my budget priced functional equipment. So good luck to you lets trade some plants or something and let all this go.
