The 3k is nice, only if you clean every so often. My maxspect never needed that much cleaning, but it is expensive as hell. I'm sure the jebao with warranty is better in the long run. A 2 year warranty is only 10 dollars, which makes the the jebao $80 on ebay. The replacement pump is only 15$ I believe. If the motor only last for 6 months (mine is 9 months old and still running), you would have thirteen uses, not including the regular pump and the warranty so 15 uses, before it almost reaches to the price of the maxspect 230. Functionality is the same, so it is not a huge loss. You would get 90 months out of this, so around 7-8 years, which hopefully I become rich by then and buy a **** ton of higher quality/advance future tech pumps. I think that's the best way to go honestly. And of course you don't need to buy 13 replacement motors. Hell you can buy 5 replacement pumps to match the 3k price and it would probably last long than the 3k with warranty.
