*shrug* I paid $30 up front for the 350 gph RIO I had...then ended up paying about $400 to replace everything it killed 1 month later when it decieded to stop working. Use it if you want, but be warned, it may have been cheap to purchase, you get exactly what you paid for. Those slide on fittings are attrocous, they are nearly impossible to get leak proof...you need top run this thing in a Res or you will be filling your system every 3 days and be cleaning a puddle off your desk. Second, forget about making the thing quiet, it rattles like a baby toy. Third, be ready for it to add heat to your system. RIOs run hot as hell for their size. Finally, good luck I hope your experience with them is better than mine.
