Cool sounds like a plan. i have 2 XP3 and 1 marineland C220.
The 2 XP3's are on my 120gal and the C220 is on my 55gal with great results. so yeah i got a good deal on my XP series, i ordered an XP3 from my bros pet shop at cost that was sweet and the same week i was out and about and i noticed a yard sale with tanks and equipment so i did a u-turn and to my amazement they had an XP3 sitting right there on the lawn and i was like i have to have that, they had a 50 buck price on it and i was like man i only have 25 bucks and they took it, i was like yay and he went on to tell me it was only a few months old. can you say score. hehehe.
But really the XP series are real easy to operate and you will enjoy the convenience of them while maintaining them.
Good luck buddy i hope you find a deal like i did.. take care..
