I got a used Rena Filstar XP3 for around $70 IIRC. Might've been like $77. I think that's a pretty good deal for a $150-200 new filter.
On the downside, it doesn't seem to include ALL of the original parts. Seems the dude bought some kinda 1-peice intake tube instead of the normal assembly of "extendable" tubing peices. Made getting the pump primed a bit harder than it had to be, but not terrible given my father's ability to jury-rig things.
Right now, working on getting his little chicken wire screen secured so that he can't get out, since we raised the water level and moved the basking dock back some so it wasn't getting sprayed by the filter output.
Oh, and I forgot to state it earlier, but the reason I think I need a 2nd tank for a 2nd turtle is that Herman bites at his own reflection in the glass, I doubt he/she would be very receptive to another turtle if he's that aggressive at his own reflection
